Replicate Multiple Elasticsearch Accounts



Replicate multiple Elasticsearch accounts to one or many databases.

CData Sync is a standalone application designed to support a variety of replication scenarios, such as replicating both sandbox and production instances into your database. It includes a web-based interface that simplifies the management of multiple Elasticsearch connections. In this article, we demonstrate how to use the web app to replicate multiple Elasticsearch accounts into a single database.

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 Replication Destinations

Using CData Sync, you can replicate data from Elasticsearch to any number of databases, both cloud-based and on-premises. In this example, we use SQLite as the replication destination to demonstrate the process. To add it as a destination, navigate to the Connections tab.

For each destination database:

  1. Click Add Connection.
  2. Select the Destinations tab and locate the SQLite connector.
  3. Click the Configure Connection icon at the end of that row to open the New Connection page. If the Configure Connection icon is not available, click the Download Connector icon to install the SQLite connector. For more information about installing new connectors, see Connections in the Help documentation.
  4. To connect to SQLite, set the following connection properties:
    • Connection Name: Enter a connection name of your choice.
    • Data Source: Enter the path to the database. You can replicate to an existing database or to a new one. The application must have permission to access the database.
  5. Once connected, click Create & Test to create, test and save the connection.

You are now connected to SQLite and can use it as both a source and a destination.

NOTE: You can use the Label feature to add a label for a source or a destination.

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.

  1. Click Add Connection.
  2. Select a source (Elasticsearch).
  3. 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.

  4. Click Connect to Elasticsearch to ensure that the connection is configured properly.
  5. Click Save & Test to save the 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, navigate to the Task tab in the Job, click Add Tasks, choose the table(s) from the list of Elasticsearch tables you wish to replicate into SQLite, and click Add Tasks again.

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 with the help of SQL queries.

The statement below caches and incrementally updates a table of Elasticsearch data:

REPLICATE Orders;

You can specify a file containing the replication queries you want to use to update a particular database. Separate the replication statements with semicolons. The following options are useful when replicating multiple Elasticsearch accounts into the same database:

  • Use a different table prefix in the REPLICATE SELECT statement:

    REPLICATE PROD_Orders SELECT * FROM Orders;
    
  • Alternatively, use a different schema:

    REPLICATE PROD.Orders SELECT * FROM Orders;
    

Schedule Your Replication

Select the Overview tab in the Job, and click Configure under Schedule. You can schedule a job to run automatically by configuring it to run at 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 disparate on-premises, cloud-based, and other databases.

Run the Replication Job

Once all the required configurations are made for the job, select the Elasticsearch table you wish to replicate and click Run. After the replication completes successfully, a notification appears, showing the time taken to run the job and the number of rows replicated.
