HBase sink with Flink

Cloudera Streaming Analytics offers HBase connector as a sink. Like this you can store the output of a real-time processing application in HBase. You must develop your application defining HBase as sink and add HBase dependency to your project.

The HBase Streaming connector has the following key features:

Automatic configuration on CDP
High throughput buffered operations
Customizable data-driven update/delete logic

To use the HBase integration, add one of the following dependencies to your project:

<dependency>
  <groupId>org.apache.flink</groupId>
  <artifactId>flink-connector-hbase-1.4</artifactId>
  <version>3.0-csa1.12.0.0</version>
</dependency>

<dependency>
  <groupId>org.apache.flink</groupId>
  <artifactId>flink-connector-hbase-2.4</artifactId>
  <version>3.0-csa1.12.0.0</version>
</dependency>

The general purpose HBase sink connector is implemented in the org.apache.flink.addons.hbase.HBaseSinkFunction class.

This is an abstract class that must be extended to define the interaction logic (mutations) with HBase. By using the BufferedMutator instance, you can implement arbitrary data driven interactions with HBase. While it is possible to run all mutations supported by the BufferedMutator interface, Cloudera strongly recommends that users should only use idempotent mutations: Put and Delete.
