Automate Kafka Data Replication to Couchbase

Always-on applications rely on automatic failover capabilities and real-time access to data. CData Sync integrates live Kafka data into your Couchbase instance, allowing you to consolidate all of your data into a single location for archiving, reporting, analytics, machine learning, artificial intelligence and more.

Configure Replication Destinations

Using CData Sync, you can replicate Kafka data to Couchbase. To add a replication destination, navigate to the Connections tab.

1. Click Add Connection.
2. Select Couchbase as a destination.
3. Enter the necessary connection properties.
   • Server - Enter either the host name or the IP address of your Couchbase server.
   • Auth Scheme - Select the authentication scheme. Basic is the default setting. For this setting, specify your login credentials:
     • User - Enter the username that you use to authenticate to Couchbase.
     • Password - Enter the password that you use to authenticate to Couchbase.
   • Couchbase Service - Select the Couchbase service that you want to use. The default service is N1QL.
   • Connection Mode - Select the connection mode that you want to use. The default mode is Direct.
   • Use SSL - Specify whether you want to use the Secure Sockets Layer (SSL) protocol. The default value is False.
   • Click Test Connection to ensure that the connection is configured properly.
   • Click Save Changes.

Configure the Kafka Connection

You can configure a connection to Kafka from the Connections tab. To add a connection to your Kafka account, navigate to the Connections tab.

1. Click Add Connection.
2. Select a source (Kafka).
3. Configure the connection properties.
   
   

   Set BootstrapServers and the Topic properties to specify the address of your Apache Kafka server, as well as the topic you would like to interact with.

   Authorization Mechanisms

   • SASL Plain: The User and Password properties should be specified. AuthScheme should be set to 'Plain'.
   • SASL SSL: The User and Password properties should be specified. AuthScheme should be set to 'Scram'. UseSSL should be set to true.
   • SSL: The SSLCert and SSLCertPassword properties should be specified. UseSSL should be set to true.
   • Kerberos: The User and Password properties should be specified. AuthScheme should be set to 'Kerberos'.

   You may be required to trust the server certificate. In such cases, specify the TrustStorePath and the TrustStorePassword if necessary.

4. Click Connect to ensure that the connection is configured properly.
5. 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 15 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 Kafka data to Couchbase.
