Use CData Sync to customize and automate Elasticsearch data replication to Azure Data Lake.
Always-on applications rely on automatic failover capabilities and real-time data access. CData Sync integrates live Elasticsearch 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.
About Elasticsearch Data Integration
Accessing and integrating live data from Elasticsearch has never been easier with CData. Customers rely on CData connectivity to:
- Access both the SQL endpoints and REST endpoints, optimizing connectivity and offering more options when it comes to reading and writing Elasticsearch data.
- Connect to virtually every Elasticsearch instance starting with v2.2 and Open Source Elasticsearch subscriptions.
- Always receive a relevance score for the query results without explicitly requiring the SCORE() function, simplifying access from 3rd party tools and easily seeing how the query results rank in text relevance.
- Search through multiple indices, relying on Elasticsearch to manage and process the query and results instead of the client machine.
Users frequently integrate Elasticsearch data with analytics tools such as Crystal Reports, Power BI, and Excel, and leverage our tools to enable a single, federated access layer to all of their data sources, including Elasticsearch.

Getting Started
Configure Azure Data Lake as a Replication Destination
Using CData Sync, you can replicate Elasticsearch 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 Elasticsearch Connection
You can configure a connection to Elasticsearch from the Connections tab. To add a connection to your Elasticsearch account, navigate to the Connections tab.
- Click Add Connection.
- Select a source (Elasticsearch).
- Configure the connection properties.
Set the Server and Port connection properties to connect. To authenticate, set the User and Password properties, PKI (public key infrastructure) properties, or both. To use PKI, set the SSLClientCert, SSLClientCertType, SSLClientCertSubject, and SSLClientCertPassword properties.
The data provider uses X-Pack Security for TLS/SSL and authentication. To connect over TLS/SSL, prefix the Server value with 'https://'. Note: TLS/SSL and client authentication must be enabled on X-Pack to use PKI.
Once the data provider is connected, X-Pack will then perform user authentication and grant role permissions based on the realms you have configured.
- 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 Elasticsearch data to PostgreSQL.
