Use CData Sync to customize and automate Azure Data Lake Storage data replication to Azure Data Lake.
Always-on applications rely on automatic failover capabilities and real-time data access. CData Sync integrates live Azure Data Lake Storage data into your Azure Data Lake instance, allowing you to consolidate all of your data into a single location for archiving, reporting, analytics, machine learning, artificial intelligence and more.
Configure Azure Data Lake as a Replication Destination
Using CData Sync, you can replicate Azure Data Lake Storage data to Azure Data Lake. To add a replication destination, navigate to the Connections tab.
- Click Add Connection.
- Select Azure Data Lake as a destination.
Enter the necessary connection properties. To connect to Azure Data Lake, set the following properties, depending on your version of Azure Data Lake Storage:
Azure Data Lake Storage Gen1
- Generation: Must be set to 1.
- Account: The name of the Azure Data Lake Store account.
- Path: The path to store the replicated file (the root directory by default).
- TenantId: The tenant ID.
- OAuthClientId: The application ID for the Azure Directory web application (see the CData Sync Help for more information).
- OAuthClientSecret: The key generated for the Azure Directory web application (see the CData Sync Help for more information).
Azure Data Lake Storage Gen2
- Generation: Must be set to 2.
- Access Key: The access key used to authenticate (see the CData Sync Help for more information).
- Account: The name of the Azure Data Lake Store account.
- FileSystem: The file systems used for this account.
- Path: The path to store the replicated file (the root directory by default).
- Click Test Connection to ensure that the connection is configured properly.
- Click Save Changes.
Configure the Azure Data Lake Storage Connection
You can configure a connection to Azure Data Lake Storage from the Connections tab. To add a connection to your Azure Data Lake Storage account, navigate to the Connections tab.
- Click Add Connection.
- Select a source (Azure Data Lake Storage).
- Configure the connection properties.
Authenticating to a Gen 1 DataLakeStore Account
Gen 1 uses OAuth 2.0 in Azure AD for authentication.
For this, an Active Directory web application is required. You can create one as follows:
To authenticate against a Gen 1 DataLakeStore account, the following properties are required:
- Schema: Set this to ADLSGen1.
- Account: Set this to the name of the account.
- OAuthClientId: Set this to the application Id of the app you created.
- OAuthClientSecret: Set this to the key generated for the app you created.
- TenantId: Set this to the tenant Id. See the property for more information on how to acquire this.
- Directory: Set this to the path which will be used to store the replicated file. If not specified, the root directory will be used.
Authenticating to a Gen 2 DataLakeStore Account
To authenticate against a Gen 2 DataLakeStore account, the following properties are required:
- Schema: Set this to ADLSGen2.
- Account: Set this to the name of the account.
- FileSystem: Set this to the file system which will be used for this account.
- AccessKey: Set this to the access key which will be used to authenticate the calls to the API. See the property for more information on how to acquire this.
- Directory: Set this to the path which will be used to store the replicated file. If not specified, the root directory will be used.
- Click Connect to ensure that the connection is configured properly.
- Click Save Changes.
Configure Replication Queries
CData Sync enables you to control replication with a point-and-click interface and with SQL queries. For each replication you wish to configure, navigate to the Jobs tab and click Add Job. Select the Source and Destination for your replication.
Replicate Entire Tables
To replicate an entire table, click Add Tables in the Tables section, choose the table(s) you wish to replicate, and click Add Selected Tables.
Customize Your Replication
You can use the Columns and Query tabs of a task to customize your replication. The Columns tab allows you to specify which columns to replicate, rename the columns at the destination, and even perform operations on the source data before replicating. The Query tab allows you to add filters, grouping, and sorting to the replication.Schedule Your Replication
In the Schedule section, you can schedule a job to run automatically, configuring the job to run after specified intervals ranging from once every 10 minutes to once every month.
Once you have configured the replication job, click Save Changes. You can configure any number of jobs to manage the replication of your Azure Data Lake Storage data to PostgreSQL.
