Azure Data Lake Storage Connection Details

Introduction

Connector Version

This documentation is based on version 25.0.9368 of the connector.

Get Started

Azure Data Lake Storage Version Support

The connector leverages the Azure Data Lake Storage API to enable bidirectional access to Azure Data Lake Storage.

Stream Azure Data Lake Storage Data

The Azure Data Lake Storage connector is designed for navigating the Azure Data Lake Storage metadata only. A variety of of stored procedures relevant to Azure Data Lake Storage data are supported as well.

This metadata typically includes details about stored objects, such as file and folder names, and excludes the actual content of the discoverable files.

If access to both the file metadata and the actual file content is needed, then the Azure Data Lake Storage connector must be used in tandem with the associated file streaming driver(s) for the filetypes stored in Azure Data Lake Storage.

The following file streaming drivers are available:

• Avro
• CSV
• Excel
• JSON
• Parquet
• REST
• XML

See the relevant file streaming driver's documentation for a configuration guide for connecting to files stored in Azure Data Lake Storage.

Establish a Connection

Connect to Azure Data Lake Storage Gen 2

To connect to a Gen 2 DataLakeStorage account, set the following properties:

• Account: The name of the storage account.
• FileSystem: The file system name used for this account. For example, the name of an Azure Blob Container.
• Directory (Optional): The path to the location where the replicated file should be stored. If no path is specified, the file is stored in the root directory.

Authenticate to Azure Data Lake Storage Gen 2

Azure Data Lake Storage Gen 2 supports five different ways to authenticate: using an Access key (AccessKey), using a Shared Access Signature (SAS), via Microsoft Entra ID OAuth (Microsoft Entra ID), via Microsoft Entra service principal (AzureServicePrincipal or AzureServicePrincipalCert), or via Managed Service Identity (AzureMSI).

Access Key

To connect using an access key, you must first obtain an available access key for the ADLS Gen2 storage account.

At the Azure portal:

1. Go to your ADLS Gen2 Storage Account.
2. Under Settings, select Access keys.
3. Copy the value for one of the available access keys to the AccessKey connection property.

When you are ready to connect, set these properties:

• AuthScheme: AccessKey.
• AccessKey: The access key value you just retrieved from the Azure Portal.

Shared Access Signature (SAS)

To connect using a Shared Access Signature, you must first generate one using the Azure Storage Explorer tool.

When you are ready to connect, set these properties:

• AuthScheme: SAS.
• SharedAccessSignature: The value of the Shared Access Signature you just generated.

Entra ID (Microsoft Entra ID)

Microsoft Entra ID is a multi-tenant, cloud-based identity and access management platform. It supports OAuth-based authentication flows that enable the driver to access Azure Data Lake Storage endpoints securely.

Authentication to Entra ID via a web application always requires that you first create and register a custom OAuth application. This enables your application to define its own redirect URI, manage credential scope, and comply with organization-specific security policies.

For full instructions on how to create and register a custom OAuth application, see Creating an Entra ID (Microsoft Entra ID) Application.

After setting AuthScheme to Microsoft Entra ID, the steps to authenticate vary, depending on the environment. For details on how to connect from desktop applications, web-based workflows, or headless systems, see the following sections..

Desktop Applications

You can authenticate from a desktop application using either the driver's embedded OAuth application or a custom OAuth application registered in Microsoft Entra ID.

Option 1: Use the Embedded OAuth Application

This is a pre-registered application, included with the driver. It simplifies setup and eliminates the need to register your own credentials and is ideal for development environments, single-user tools, or any setup where quick and easy authentication is preferred.

Set the following connection properties:

• AuthScheme: Microsoft Entra ID
• InitiateOAuth:
  • GETANDREFRESH – Use for the initial login. Launches the login page and saves tokens.
  • REFRESH – Use this setting when you have already obtained valid access and refresh tokens. Reuses stored tokens without prompting the user again.

When you connect, the driver opens the Microsoft Entra sign-in page in your default browser. After signing in and granting access, the driver retrieves the access and refresh tokens and saves them to the path specified by OAuthSettingsLocation.

Option 2: Use a Custom OAuth Application

If your organization requires more control, such as managing security policies, redirect URIs, or application branding, you can instead register a custom OAuth application in Microsoft Entra ID and provide its values during connection.

During registration, record the following values:

• OAuthClientId: The client ID that was generated when you registered your custom OAuth application.
• OAuthClientSecret: The client secret that was that was generated when you registered your custom OAuth application.
• CallbackURL: A redirect URI you defined during application registration.

For full instructions on how to register a custom OAuth application and configure redirect URIs, see Creating an Entra ID (Microsoft Entra ID) Application.

Set the following connection properties:

• AuthScheme: Microsoft Entra ID
• InitiateOAuth:
  • GETANDREFRESH – Use for the initial login. Launches the login page and saves tokens.
  • REFRESH – Use this setting when you have already obtained valid access and refresh tokens. Reuses stored tokens without prompting the user again.
• OAuthClientId: The client ID that was generated when you registered your custom OAuth application.
• OAuthClientSecret: The client secret that was generated when you registered your custom OAuth application.
• CallbackURL: A redirect URI you defined during application registration.

After authentication, tokens are saved to OAuthSettingsLocation. These values persist across sessions and are used to automatically refresh the access token when it expires, so you don't need to log in again on future connections.

Microsoft Entra service principal

Service principals are security objects within a Microsoft Entra ID (Microsoft Entra ID) application that define what that application can do within a specific tenant. Service principals are created in the Entra admin center, also accessible through the Azure portal. As part of the creation process we also specify whether the service principal will access Entra resources via a client secret or a certificate.

Instead of being tied to a particular user, service principal permissions are based on the roles assigned to them. These roles determine which resources the application can access and which operations it can perform.

When authenticating using a service principal, you must register an application with an Entra tenant, as described in Creating a Service Principal App in Entra ID (Microsoft Entra ID).

This subsection describes properties you must set before you can connect. These vary, depending on whether you will authenticate via a client secret or a certificate.

Authentication with Client Secret

• AuthScheme: AzureServicePrincipal.
• AzureTenant: The Microsoft Entra ID tenant to which you will connect.
• OAuthClientId: The client ID in your application settings.
• OAuthClientSecret: The client secret in your application settings.
• InitiateOAuth: GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.

Authentication with Certificate

• AuthScheme: AzureServicePrincipalCert.
• AzureTenant: The Microsoft Entra ID tenant to which you will connect.
• OAuthClientId: The client ID in your application settings.
• OAuthJWTCert: The JWT Certificate store.
• OAuthJWTCertType: The JWT Certificate store type.
• InitiateOAuth: GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.

Managed Service Identity (MSI)

If you are running Azure Data Lake Storage on an Azure VM and want to automatically obtain Managed Service Identity (MSI) credentials to connect, set AuthScheme to AzureMSI.

User-Managed Identities

To obtain a token for a managed identity, use the OAuthClientId property to specify the managed identity's client_id.

If your VM has multiple user-assigned managed identities, you must also specify OAuthClientId.

Create an Entra ID (Microsoft Entra ID) Application

Create an Entra ID (Microsoft Entra ID) Application

Azure Data Lake Storage supports OAuth-based authentication using Microsoft Entra ID. If you will connect via a web application and want to authenticate via Entra ID, you must first register a custom OAuth application in the Entra Admin Center, as described below.

If you will connect via a desktop application or headless machine, you can authenticate using Azure Data Lake Storage's built-in embedded application credentials, which use branding. However, custom OAuth applications are also compatible with desktop and headless authentication flows, and may be preferable for production deployments or environments requiring strict policy control.

Register the Application

To register an OAuth application in Microsoft Entra ID, follow these steps:

1. Go to https://portal.azure.com.

2. In the left-hand navigation pane, select Microsoft Entra ID > App registrations.

3. Click New registration.

4. Enter a name for the application.

5. Specify the types of accounts this application should support:

   • For private-use applications, select Accounts in this organization directory only.
   • For distributed applications, select one of the multi-tenant options.

1. Set the redirect URI to http://localhost:33333 (default), or use another URI appropriate for your deployment.

   When using a custom redirect URI set a CallbackURL connection property; in those cases, set it to match this URI exactly.

2. Click Register. The application management screen opens. Record these values for later use:

   • Application (client) ID is used for OAuthClientId
   • Directory (tenant) ID is used for AzureTenant

3. Go to Certificates & Secrets. Click New Client Secret, set the desired expiration, and save the generated value. This value will only be shown once — record it to use with OAuthClientSecret.

4. Select 'Windows Azure Service Management API' along with 'Azure Data Lake' and add the Have full access to the Azure Data Lake service permission.

5. To confirm, click Add permissions.

Create a Service Principal App in Entra ID (Microsoft Entra ID)

Create a Service Principal App in Entra ID (Microsoft Entra ID)

Azure Data Lake Storage supports Service Principal-based authentication, which is role-based. This means that the Service Principal's permissions are determined by the roles assigned to it. The roles specify what resources the Service Principal can access and which operations it can perform.

If you want to use a Service Principal to authenticate to Azure Data Lake Storage, you must create a custom application in Microsoft Entra ID.

To enable Service Principal authentication:

• Confirm that you have permission to register applications and assign roles in your tenant.
• Register a new application and configure credentials and permissions in the Entra Admin Center.

Register the Application

1. Go to https://portal.azure.com.
2. In the left-hand navigation pane, select Microsoft Entra ID > App registrations.
3. Click New registration.
4. Enter a name for the application.
5. Select the desired tenant setup. Since this custom application is for Service Principal use, choose Any Microsoft Entra ID tenant – Multitenant.
6. Click Register. The application management screen opens. Note the value in Application (client) ID as the OAuthClientId and the Directory (tenant) ID as the AzureTenant
7. Navigate to Certificates & Secrets and define the application authentication type. Two types of authentication are available: certificate (recommended) or client secret
   • For certificate authentication: In Certificates & Secrets, select Upload certificate, then upload the certificate from your local machine. For more information on creating a self-signed certificate, see Create a self-signed certificate
   • For creating a new client secret: In Certificates & Secrets, select New Client Secret for the application and specify its duration. After the client secret is saved, Azure Data Lake Storage displays the key value. This value is displayed only once, so be sure to record it for future use. Use this value for the OAuthClientSecret
8. Navigate to Authentication and select the Access tokens option.
9. Select 'Windows Azure Service Management API' along with 'Azure Data Lake' and add the Have full access to the Azure Data Lake service permission.
10. Save your changes.
11. If you specified permissions that require admin consent (such as the Application Permissions), you can grant them from the current tenant on the API Permissions page.

Grant Admin Consent

Some custom applications require administrative permissions to operate within a Microsoft Entra ID tenant. This is especially true for applications that use Application permissions, which allow the app to run without a signed-in user. Admin consent can be granted when creating a new application, by adding relevant permissions marked as "Admin Consent Required".

Admin consent is also required to use Client Credentials in the authentication flow.

These permissions must be granted by an admin. To grant admin consent:

1. Log in to https://portal.azure.com with an administrator account.
2. Navigate to Microsoft Entra ID > App registrations and select your registered application.
3. Navigate to API permissions.
4. Review the permissions listed under Application permissions. Ensure the necessary API scopes are included for your use case.
5. Click Grant admin consent to approve the requested permissions.

This gives your application permissions on the tenant under which it was created.

Consent for Client Credentials

OAuth supports the use of client credentials to authenticate. In a client credentials authentication flow, credentials are created for the authenticating application itself. The auth flow acts just like the usual auth flow, except that there is no prompt for an associated user to provide credentials. All tasks accepted by the application are executed outside of the context of a default user.

1. Log in to https://portal.azure.com
2. Create a custom OAuth application, as described above.
3. Navigate to App Registrations.
4. Find the application you just created, and open API Permissions.
5. Select the Microsoft Graph permissions. There are two distinct sets of permissions: Delegated and Application.
6. For use with Service Principal, specify Application permissions.
7. Select the permissions you require for your integration.

Fine-Tuning Data Access

Fine Tuning Data Access

To gain more control over the data returned from Azure Data Lake Storage Gen2's ADLSGen2 schema, set IncludeSubDirectories. This property specifies whether the connector should list the subdirectories' paths in the Resources view.

Important Notes

Configuration Files and Their Paths

• All references to adding configuration files and their paths refer to files and locations on the Jitterbit agent where the connector is installed. These paths are to be adjusted as appropriate depending on the agent and the operating system. If multiple agents are used in an agent group, identical files will be required on each agent.

Advanced Features

This section details a selection of advanced features of the Azure Data Lake Storage connector.

User Defined Views

The connector supports the use of user defined views, virtual tables whose contents are decided by a pre-configured user defined query. These views are useful when you cannot directly control queries being issued to the drivers. For an overview of creating and configuring custom views, see User Defined Views.

SSL Configuration

Use SSL Configuration to adjust how connector handles TLS/SSL certificate negotiations. You can choose from various certificate formats. For further information, see the SSLServerCert property under "Connection String Options".

Proxy

To configure the connector using private agent proxy settings, select the Use Proxy Settings checkbox on the connection configuration screen.

Query Processing

The connector offloads as much of the SELECT statement processing as possible to Azure Data Lake Storage and then processes the rest of the query in memory (client-side).

For further information, see Query Processing.

Log

For an overview of configuration settings that can be used to refine logging, see Logging. Only two connection properties are required for basic logging, but there are numerous features that support more refined logging, which enables you to use the LogModules connection property to specify subsets of information to be logged.

User Defined Views

The Azure Data Lake Storage connector supports the use of user defined views: user-defined virtual tables whose contents are decided by a preconfigured query. User defined views are useful in situations where you cannot directly control the query being issued to the driver; for example, when using the driver from Jitterbit.

Use a user defined view to define predicates that are always applied. If you specify additional predicates in the query to the view, they are combined with the query already defined as part of the view.

There are two ways to create user defined views:

• Create a JSON-formatted configuration file defining the views you want.
• DDL statements.

Define Views Using a Configuration File

User defined views are defined in a JSON-formatted configuration file called UserDefinedViews.json. The connector automatically detects the views specified in this file.

You can also have multiple view definitions and control them using the UserDefinedViews connection property. When you use this property, only the specified views are seen by the connector.

This user defined view configuration file is formatted so that each root element defines the name of a view, and includes a child element, called query, which contains the custom SQL query for the view.

For example:

{
    "MyView": {
        "query": "SELECT * FROM Resources WHERE MyColumn = 'value'"
    },
    "MyView2": {
        "query": "SELECT * FROM MyTable WHERE Id IN (1,2,3)"
    }
}

Use the UserDefinedViews connection property to specify the location of your JSON configuration file. For example:

"UserDefinedViews", "C:\Users\yourusername\Desktop\tmp\UserDefinedViews.json"

Define Views Using DDL Statements

The connector is also capable of creating and altering the schema via DDL Statements such as CREATE LOCAL VIEW, ALTER LOCAL VIEW, and DROP LOCAL VIEW.

Create a View

To create a new view using DDL statements, provide the view name and query as follows:

CREATE LOCAL VIEW [MyViewName] AS SELECT * FROM Customers LIMIT 20;

If no JSON file exists, the above code creates one. The view is then created in the JSON configuration file and is now discoverable. The JSON file location is specified by the UserDefinedViews connection property.

Alter a View

To alter an existing view, provide the name of an existing view alongside the new query you would like to use instead:

ALTER LOCAL VIEW [MyViewName] AS SELECT * FROM Customers WHERE TimeModified > '3/1/2020';

The view is then updated in the JSON configuration file.

Drop a View

To drop an existing view, provide the name of an existing schema alongside the new query you would like to use instead.

DROP LOCAL VIEW [MyViewName]

This removes the view from the JSON configuration file. It can no longer be queried.

Schema for User Defined Views

In order to avoid a view's name clashing with an actual entity in the data model, user defined views are exposed in the UserViews schema by default. To change the name of the schema used for UserViews, reset the UserViewsSchemaName property.

Work with User Defined Views

For example, a SQL statement with a user defined view called UserViews.RCustomers only lists customers in Raleigh:

SELECT * FROM Customers WHERE City = 'Raleigh';

An example of a query to the driver:

SELECT * FROM UserViews.RCustomers WHERE Status = 'Active';

Resulting in the effective query to the source:

SELECT * FROM Customers WHERE City = 'Raleigh' AND Status = 'Active';

That is a very simple example of a query to a user defined view that is effectively a combination of the view query and the view definition. It is possible to compose these queries in much more complex patterns. All SQL operations are allowed in both queries and are combined when appropriate.

SSL Configuration

Customize the SSL Configuration

By default, the connector attempts to negotiate TLS with the server. The server certificate is validated against the default system trusted certificate store. You can override how the certificate gets validated using the SSLServerCert connection property.

To specify another certificate, see the SSLServerCert connection property.

Data Model

Overview

This section shows the available API objects and provides more information on executing SQL to Azure Data Lake Storage APIs.

Key Features

• The connector models Azure Data Lake Storage entities like documents, folders, and groups as relational views, allowing you to write SQL to query Azure Data Lake Storage data.
• Stored procedures allow you to execute operations to Azure Data Lake Storage.
• Live connectivity to these objects means any changes to your Azure Data Lake Storage account are immediately reflected when using the connector.

Views

Views describes the available views. Views are statically defined to model Resources and Permissions.

Stored Procedures

Stored Procedures are function-like interfaces to Azure Data Lake Storage. Stored procedures allow you to execute operations to Azure Data Lake Storage, including downloading documents and moving envelopes.

Views

Views are similar to tables in the way that data is represented; however, views are read-only.

Queries can be executed against a view as if it were a normal table.

Azure Data Lake Storage Connector Views

FileSystems

Lists all filesystems.

Columns

Resources

Lists the contents of the supplied path.

Columns

Pseudo-Columns

Pseudo column fields are used in the WHERE clause of SELECT statements and offer a more granular control over the tuples that are returned from the data source.

Stored Procedures

Stored procedures are function-like interfaces that extend the functionality of the connector beyond simple SELECT operations with Azure Data Lake Storage.

Stored procedures accept a list of parameters, perform their intended function, and then return any relevant response data from Azure Data Lake Storage, along with an indication of whether the procedure succeeded or failed.

Stored Procedure Specific Information

The behavior of this stored procedure depends on the nature of the FilePath parameter and is influenced by the MaxThreads connection property, which defines the maximum number of threads to use during the upload process:

• If FilePath points to a single file, the driver uploads it in parallel chunks. The size of each chunk is determined by the ChunkSize connection property, and the upload is distributed across multiple threads based on the value of MaxThreads.
• If FilePath points to a directory, the driver uploads each file in the directory in parallel, using one thread per file. In this mode, multipart chunking is not applied to individual files.

Examples:

• Uploading a single file in parallel using multiple threads and chunking:

      EXECUTE UploadFile FilePath = 'C:/Users/User/Desktop/SampleUploadtest.txt'
  

• Uploading all files in a directory in parallel, one thread per file (no chunking):

      EXECUTE UploadFile FilePath = 'C:/Users/User/Desktop/'

• When AuthScheme is set to AzureServicePrincipal or AzureServicePrincipalCert
• When AuthScheme is Microsoft Entra ID and the user account belongs to multiple tenants

You can provide the tenant value in one of two formats:

• A domain name (for example, contoso.onmicrosoft.com)
• A directory (tenant) ID in GUID format (for example, c9d7b8e4-1234-4f90-bc1a-2a28e0f9e9e0)

Specifying the tenant explicitly ensures that the authentication request is routed to the correct directory, which is especially important when a user belongs to multiple tenants or when using service principal–based authentication.

If this value is omitted when required, authentication may fail or connect to the wrong tenant. This can result in errors such as unauthorized or resource not found.

AzureEnvironment

Specifies the Azure network environment to which you will connect. Must be the same network to which your Azure account was added.

Possible Values

GLOBAL, CHINA, USGOVT, USGOVTDOD

Data Type

string

Default Value

GLOBAL

Remarks

Required if your Azure account is part of a different network than the Global network, such as China, USGOVT, or USGOVTDOD.

OAuth

This section provides a complete list of OAuth properties you can configure.

InitiateOAuth

Specifies the process for obtaining or refreshing the OAuth access token, which maintains user access while an authenticated, authorized user is working.

Possible Values

OFF, REFRESH, GETANDREFRESH

Data Type

string

Default Value

OFF

Remarks

OAuth is an authorization framework that enables applications to obtain limited access to user accounts on an HTTP service. The OAuth flow defines the method to be used for logging in users, exchanging their credentials for an OAuth access token to be used for authentication, and providing limited access to applications.

Azure Data Lake Storage supports the following options for initiating OAuth access:

1. OFF: No automatic OAuth flow initiation. The OAuth flow is handled entirely by the user, who will take action to obtain their OAuthAccessToken. Note that with this setting the user must refresh the token manually and reconnect with an updated OAuthAccessToken property when the current token expires.
2. GETANDREFRESH: The OAuth flow is handled entirely by the connector. If a token already exists, it is refreshed when necessary. If no token currently exists, it will be obtained by prompting the user to login.
3. REFRESH: The user handles obtaining the OAuth Access Token and sets up the sequence for refreshing the OAuth Access Token. (The user is never prompted to log in to authenticate. After the user logs in, the connector handles the refresh of the OAuth Access Token.

OAuthClientId

Specifies the client ID (also known as the consumer key) assigned to your custom OAuth application. This ID is required to identify the application to the OAuth authorization server during authentication.

Data Type

string

Default Value

""

Remarks

This property is required when using a custom OAuth application, such as in web-based authentication flows, service-based authentication, or certificate-based flows that require application registration. It is also required if an embedded OAuth application is not available for the driver. When an embedded OAuth application is available, this value may already be provided by the connector and not require manual entry.

This value is generally used alongside other OAuth-related properties such as OAuthClientSecret and OAuthSettingsLocation when configuring an authenticated connection.

OAuthClientId is one of the key connection parameters that need to be set before users can authenticate via OAuth. You can typically find this value in your identity provider’s application registration settings. Look for a field labeled Client ID, Application ID, or Consumer Key.

While the client ID is not considered a confidential value like a client secret, it is still part of your application's identity and should be handled carefully. Avoid exposing it in public repositories or shared configuration files.

OAuthClientSecret

Specifies the client secret assigned to your custom OAuth application. This confidential value is used to authenticate the application to the OAuth authorization server.

Data Type

string

Default Value

""

Remarks

This property is required when using a custom OAuth application in any flow that requires secure client authentication, such as web-based OAuth, service-based connections, or certificate-based authorization flows. It is not required when using an embedded OAuth application.

The client secret is used during the token exchange step of the OAuth flow, when the driver requests an access token from the authorization server. If this value is missing or incorrect, authentication will fail, and the server may return an invalid_client or unauthorized_client error.

OAuthClientSecret is one of the key connection parameters that need to be set before users can authenticate via OAuth. You can obtain this value from your identity provider when registering the OAuth application. It may be referred to as the client secret, application secret, or consumer secret.

This value should be stored securely and never exposed in public repositories, scripts, or unsecured environments. Client secrets may also expire after a set period. Be sure to monitor expiration dates and rotate secrets as needed to maintain uninterrupted access.

OAuthAccessToken

Specifies the OAuth access token used to authenticate requests to the data source. This token is issued by the authorization server after a successful OAuth exchange.

Data Type

string

Default Value

""

Remarks

The OAuthAccessToken is a temporary credential that authorizes access to protected resources. It is typically returned by the identity provider after the user or client application completes an OAuth authentication flow. This property is most commonly used in automated workflows or custom OAuth implementations where you want to manage token handling outside of the driver.

The OAuth access token has a server-dependent timeout, limiting user access. This is set using the OAuthExpiresIn property. However, it can be reissued between requests to keep access alive as long as the user keeps working.

If InitiateOAuth is set to REFRESH, we recommend that you also set both OAuthExpiresIn and OAuthTokenTimestamp. The connector uses these properties to determine when the token expires so it can refresh most efficiently. If OAuthExpiresIn and OAuthTokenTimestamp are not specified, the connector refreshes the token immediately.

Access tokens should be treated as sensitive credentials and stored securely. Avoid exposing them in logs, scripts, or configuration files that are not access-controlled.

OAuthSettingsLocation

The location of the settings file where OAuth values are saved when InitiateOAuth is set to GETANDREFRESH or REFRESH. Alternatively, you can hold this location in memory by specifying a value starting with 'memory://'.

Data Type

string

Default Value

%APPDATA%\\CData\\Acumatica Data Provider\\OAuthSettings.txt

Remarks

When InitiateOAuth is set to GETANDREFRESH or REFRESH, the driver saves OAuth values to avoid requiring the user to manually enter OAuth connection properties and to allow the credentials to be shared across connections or processes.

Instead of specifying a file path, you can use memory storage. Memory locations are specified by using a value starting with 'memory://' followed by a unique identifier for that set of credentials (for example, memory://user1). The identifier can be anything you choose but should be unique to the user. Unlike file-based storage, where credentials persist across connections, memory storage loads the credentials into static memory, and the credentials are shared between connections using the same identifier for the life of the process. To persist credentials outside the current process, you must manually store the credentials prior to closing the connection. This enables you to set them in the connection when the process is started again. You can retrieve OAuth property values with a query to the sys_connection_props system table. If there are multiple connections using the same credentials, the properties are read from the previously closed connection.

The default location is "%APPDATA%\\CData\\Acumatica Data Provider\\OAuthSettings.txt" with %APPDATA% set to the user's configuration directory. The default values are

• Windows: "register://%DSN"
• Unix: "%AppData%..."

where DSN is the name of the current DSN used in the open connection.

The following table lists the value of %APPDATA% by OS:

CallbackURL

Identifies the URL users return to after authenticating to Azure Data Lake Storage via OAuth. (Custom OAuth applications only.).

Data Type

string

Default Value

""

Remarks

If you created a custom OAuth application, the OAuth authorization server redirects the user to this URL during the authentication process. This value must match the callback URL you specified when you Configured the custom OAuth application.

OAuthVerifier

Specifies a verifier code returned from the OAuthAuthorizationURL . Used when authenticating to OAuth on a headless server, where a browser can't be launched. Requires both OAuthSettingsLocation and OAuthVerifier to be set.

Data Type

string

Default Value

""

OAuthRefreshToken

Specifies the OAuth refresh token used to request a new access token after the original has expired.

Data Type

string

Default Value

""

Remarks

The refresh token is used to obtain a new access token when the current one expires. It enables seamless authentication for long-running or automated workflows without requiring the user to log in again. This property is especially important in headless, CI/CD, or server-based environments where interactive authentication is not possible.

The refresh token is typically obtained during the initial OAuth exchange by calling the GetOAuthAccessToken stored procedure. After that, it can be set using this property to enable automatic token refresh, or passed to the RefreshOAuthAccessToken stored procedure if you prefer to manage the refresh manually.

When InitiateOAuth is set to REFRESH, the driver uses this token to retrieve a new access token automatically. After the first refresh, the driver saves updated tokens in the location defined by OAuthSettingsLocation, and uses those values for subsequent connections.

The OAuthRefreshToken should be handled securely and stored in a trusted location. Like access tokens, refresh tokens can expire or be revoked depending on the identity provider’s policies.

OAuthExpiresIn

Specifies the duration in seconds, of an OAuth Access Token's lifetime. The token can be reissued to keep access alive as long as the user keeps working.

Data Type

string

Default Value

""

Remarks

The OAuth Access Token is assigned to an authenticated user, granting that user access to the network for a specified period of time. The access token is used in place of the user's login ID and password, which stay on the server.

An access token created by the server is only valid for a limited time. OAuthExpiresIn is the number of seconds the token is valid from when it was created. For example, a token generated at 2024-01-29 20:00:00 UTC that expires at 2024-01-29 21:00:00 UTC (an hour later) would have an OAuthExpiresIn value of 3600, no matter what the current time is.

To determine how long the user has before the Access Token will expire, use OAuthTokenTimestamp.

OAuthTokenTimestamp

Displays a Unix epoch timestamp in milliseconds that shows how long ago the current Access Token was created.

Data Type

string

Default Value

""

Remarks

The OAuth Access Token is assigned to an authenticated user, granting that user access to the network for a specified period of time. The access token is used in place of the user's login ID and password, which stay on the server.

An access token created by the server is only valid for a limited time. OAuthTokenTimestamp is the Unix timestamp when the server created the token. For example, OAuthTokenTimestamp=1706558400 indicates the OAuthAccessToken was generated by the server at 2024-01-29 20:00:00 UTC.

JWT OAuth

This section provides a complete list of JWT OAuth properties you can configure.

OAuthJWTCert

Supplies the name of the client certificate's JWT Certificate store.

Data Type

string

Default Value

""

Remarks

The OAuthJWTCertType field specifies the type of the certificate store specified in OAuthJWTCert. If the store is password-protected, use OAuthJWTCertPassword to supply the password..

OAuthJWTCert is used in conjunction with the OAuthJWTCertSubject field in order to specify client certificates.

If OAuthJWTCert has a value, and OAuthJWTCertSubject is set, the Azure Data Lake Storage connector initiates a search for a certificate. For further information, see OAuthJWTCertSubject.

Designations of certificate stores are platform-dependent.

Notes

• The most common User and Machine certificate stores in Windows include:

  • MY: A certificate store holding personal certificates with their

    associated private keys.

  • CA: Certifying authority certificates.

  • ROOT: Root certificates.

  • SPC: Software publisher certificates.

  • In Java, the certificate store normally is a file containing certificates and optional private keys.
  • When the certificate store type is PFXFile, this property must be set to the name of the file.
  • When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e. PKCS12 certificate store).

OAuthJWTCertType

Identifies the type of key store containing the JWT Certificate.

Possible Values

USER, MACHINE, PFXFILE, PFXBLOB, JKSFILE, JKSBLOB, PEMKEY_FILE, PEMKEY_BLOB, PUBLIC_KEY_FILE, PUBLIC_KEY_BLOB, SSHPUBLIC_KEY_FILE, SSHPUBLIC_KEY_BLOB, P7BFILE, PPKFILE, XMLFILE, XMLBLOB, BCFKSFILE, BCFKSBLOB

Data Type

string

Default Value

USER

Remarks

OAuthJWTCertPassword

Provides the password for the OAuth JWT certificate used to access a password-protected certificate store. If the certificate store does not require a password, leave this property blank.

Data Type

string

Default Value

""

Remarks

This property specifies the password needed to open a password-protected certificate store. To determine if a password is necessary, refer to the documentation or configuration for your specific certificate store.

OAuthJWTCertSubject

Identifies the subject of the OAuth JWT certificate used to locate a matching certificate in the store. Supports partial matches and the wildcard '*' to select the first certificate.

Data Type

string

Default Value

*

Remarks

The value of this property is used to locate a matching certificate in the store. The search process works as follows:

• If an exact match for the subject is found, the corresponding certificate is selected.
• If no exact match is found, the store is searched for certificates whose subjects contain the property value.
• If no match is found, no certificate is selected.

You can set the value to '*' to automatically select the first certificate in the store. The certificate subject is a comma-separated list of distinguished name fields and values. For example: CN=www.server.com, OU=test, C=US, E=example@jbexample.com. Common fields include:

If a field value contains a comma, enclose it in quotes. For example: "O=ACME, Inc.".

SSL

This section provides a complete list of SSL properties you can configure.

SSLServerCert

Specifies the certificate to be accepted from the server when connecting using TLS/SSL.

Data Type

string

Default Value

""

Remarks

If using a TLS/SSL connection, this property can be used to specify the TLS/SSL certificate to be accepted from the server. Any other certificate that is not trusted by the machine is rejected.

This property can take the following forms:

If not specified, any certificate trusted by the machine is accepted.

Certificates are validated as trusted by the machine based on the System's trust store. The trust store used is the 'javax.net.ssl.trustStore' value specified for the system. If no value is specified for this property, Java's default trust store is used (for example, JAVA_HOME\lib\security\cacerts).

Use '*' to signify to accept all certificates. Note that this is not recommended due to security concerns.

Schema

This section provides a complete list of schema properties you can configure.

Location

Specifies the location of a directory containing schema files that define tables, views, and stored procedures. Depending on your service's requirements, this may be expressed as either an absolute path or a relative path.

Data Type

string

Default Value

%APPDATA%\ADLS Data Provider\Schema

Remarks

The Location property is only needed if you want to either customize definitions (for example, change a column name, ignore a column, etc.) or extend the data model with new tables, views, or stored procedures.

• Each schema should have its own folder, named for that schema.
• All schema folders should be contained in a parent folder.

Location should always be set to the parent folder, and not to an individual schema's folder.

If left unspecified, the default location is %APPDATA%\ADLS Data Provider\Schema, where %APPDATA% is set to the user's configuration directory:

BrowsableSchemas

Optional setting that restricts the schemas reported to a subset of all available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC.

Data Type

string

Default Value

""

Remarks

Listing all available database schemas can take extra time, thus degrading performance. Providing a list of schemas in the connection string saves time and improves performance.

Tables

Optional setting that restricts the tables reported to a subset of all available tables. For example, Tables=TableA,TableB,TableC.

Data Type

string

Default Value

""

Remarks

Listing all available tables from some databases can take extra time, thus degrading performance. Providing a list of tables in the connection string saves time and improves performance.

If there are lots of tables available and you already know which ones you want to work with, you can use this property to restrict your viewing to only those tables. To do this, specify the tables you want in a comma-separated list. Each table should be a valid SQL identifier with any special characters escaped using square brackets, double-quotes or backticks. For example, Tables=TableA,[TableB/WithSlash],WithCatalog.WithSchema.`TableC With Space`.

Views

Optional setting that restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC.

Data Type

string

Default Value

""

Remarks

Listing all available views from some databases can take extra time, thus degrading performance. Providing a list of views in the connection string saves time and improves performance.

If there are lots of views available and you already know which ones you want to work with, you can use this property to restrict your viewing to only those views. To do this, specify the views you want in a comma-separated list. Each view should be a valid SQL identifier with any special characters escaped using square brackets, double-quotes or backticks. For example, Views=ViewA,[ViewB/WithSlash],WithCatalog.WithSchema.`ViewC With Space`.

Miscellaneous

This section provides a complete list of miscellaneous properties you can configure.

ChunkSize

The size of chunks (in MB) to use when uploading large files.

Data Type

int

Default Value

16

Remarks

This property determines the size, in megabytes, of each data block the connector uploads when transferring large files to Azure Data Lake Storage Gen2.

If this property is left unset, the connector uses the default value: 16 MB.

If a file exceeds the chunk size, it is divided into multiple blocks of the specified size and uploaded sequentially.

Increasing the chunk size can improve upload performance for large files, but may increase memory usage. Decreasing it can reduce memory use, but may result in slower uploads.

This setting is only applied to upload operations and does not affect file downloads.

MaxRows

Specifies the maximum rows returned for queries without aggregation or GROUP BY.

Data Type

int

Default Value

-1

Remarks

This property sets an upper limit on the number of rows the connector returns for queries that do not include aggregation or GROUP BY clauses. This limit ensures that queries do not return excessively large result sets by default.

When a query includes a LIMIT clause, the value specified in the query takes precedence over the MaxRows setting. If MaxRows is set to "-1", no row limit is enforced unless a LIMIT clause is explicitly included in the query.

This property is useful for optimizing performance and preventing excessive resource consumption when executing queries that could otherwise return very large datasets.

MaxThreads

Specifies the number of concurrent requests.

Data Type

string

Default Value

5

Remarks

This property allows you to issue multiple requests simultaneously, thereby improving performance.

Other

Specifies additional hidden properties for specific use cases. These are not required for typical provider functionality. Use a semicolon-separated list to define multiple properties.

Data Type

string

Default Value

""

Remarks

This property allows advanced users to configure hidden properties for specialized scenarios. These settings are not required for normal use cases but can address unique requirements or provide additional functionality. Multiple properties can be defined in a semicolon-separated list.

Specify multiple properties in a semicolon-separated list.

Integration and Formatting

PseudoColumns

Specifies the pseudocolumns to expose as table columns. Use the format 'TableName=ColumnName;TableName=ColumnName'. The default is an empty string, which disables this property.

Data Type

string

Default Value

""

Remarks

This property allows you to define which pseudocolumns the connector exposes as table columns.

To specify individual pseudocolumns, use the following format: "Table1=Column1;Table1=Column2;Table2=Column3"

To include all pseudocolumns for all tables use: "*=*"

Timeout

Specifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error. The default is 60 seconds. Set to 0 to disable the timeout.

Data Type

int

Default Value

60

Remarks

This property controls the maximum time, in seconds, that the connector waits for an operation to complete before canceling it. If the timeout period expires before the operation finishes, the connector cancels the operation and throws an exception.

The timeout applies to each individual communication with the server rather than the entire query or operation. For example, a query could continue running beyond the timeout value if each paging call completes within the timeout limit.

Setting this property to 0 disables the timeout, allowing operations to run indefinitely until they succeed or fail due to other conditions such as server-side timeouts, network interruptions, or resource limits on the server. Use this property cautiously to avoid long-running operations that could degrade performance or result in unresponsive behavior.

UserDefinedViews

Specifies a filepath to a JSON configuration file defining custom views. The provider automatically detects and uses the views specified in this file.

Data Type

string

Default Value

""

Remarks

This property allows you to define and manage custom views through a JSON-formatted configuration file called UserDefinedViews.json. These views are automatically recognized by the connector and enable you to execute custom SQL queries as if they were standard database views. The JSON file defines each view as a root element with a child element called "query", which contains the SQL query for the view. For example:

{
    "MyView": {
        "query": "SELECT * FROM Resources WHERE MyColumn = 'value'"
    },
    "MyView2": {
        "query": "SELECT * FROM MyTable WHERE Id IN (1,2,3)"
    }

}

You can define multiple views in a single file and specify the filepath using this property. For example: UserDefinedViews=C:\Path\To\UserDefinedViews.json. When you use this property, only the specified views are seen by the connector.

Refer to User Defined Views for more information.
