Automated Continuous Elasticsearch Replication to IBM DB2
Use CData Sync for automated, continuous, customizable Elasticsearch replication to IBM DB2.
Always-on applications rely on automatic failover capabilities and real-time data access. CData Sync integrates live Elasticsearch data into your IBM DB2 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 IBM DB2 as a Replication Destination
Using CData Sync, you can replicate Elasticsearch data to IBM DB2. To add a replication destination, navigate to the Connections tab.
- Click Add Connection.
- Select the Destinations tab and locate the IBM DB2 connector.
- Click the Configure Connection icon at the end of that row to open the New Connection page. Sync requires the db2jcc.jar driver to connect to your DB2 database. If you have not done so already, make sure to download the native DB2 JDBC driver from DB2 JDBC Driver Versions and Downloads web page.
- Copy the JDBC driver into the lib directory.
- Microsoft Windows: C:\Program Files\CData\CData Sync\lib
- UNIX or Mac OS X: ~/CData/CData Sync/lib
- To connect to IBM DB2, set the following connection properties:
- Connection Name: Enter a connection name of your choice for the IBM DB2 connection.
- Server: Enter either the host name or the IP address of the server that hosts your IBM DB2 instance.
- Port: Enter the port number of the server that hosts your instance of IBM DB2. The default port value is 50000.
- Database: Set this to the database you want to read from and write to.
- User: Set this to the database user.
- Password: Set this to the user's password.
- Once connected, click Create & Test to create, test and save the connection.
You are now connected to IBM DB2 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.
In this article, we will demonstrate how to load Elasticsearch data into IBM DB2 and utilize it as 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.
- 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 Elasticsearch to ensure that the connection is configured properly.
- 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 IBM DB2, 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.
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 IBM DB2.
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.
