[FLINK-22748] Allow dynamic target topic selection in SQL Kafka sinks (#109)

[FLINK-22748][connector-kafka] Allow dynamic target topic selection in SQL Kafka sinks

Allows writing to different Kafka topics based on the topic metadata column value in SQL, and updates the Table API's KafkaDynamicSink to accept a List<String> topics instead of String topic as well as support topic-pattern. The list acts as an allow-list of acceptable values for the topic metadata column. topic-pattern for sinks is a pattern that must match topic metadata column values, or else an error is thrown.

If a single topic is provided, it is used by default for the target topic to produce to
If a list is provided, only that list of topics can be produced to
If a topic pattern is provided, it must match topic metadata column values

Apache Flink Kafka Connector

This repository contains the official Apache Flink Kafka connector.

Apache Flink

Apache Flink is an open source stream processing framework with powerful stream- and batch-processing capabilities.

Learn more about Flink at https://flink.apache.org/

Building the Apache Flink Kafka Connector from Source

Prerequisites:

  • Unix-like environment (we use Linux, Mac OS X)
  • Git
  • Maven (we recommend version 3.8.6)
  • Java 11
git clone https://github.com/apache/flink-connector-kafka.git
cd flink-connector-kafka
mvn clean package -DskipTests

The resulting jars can be found in the target directory of the respective module.

Developing Flink

The Flink committers use IntelliJ IDEA to develop the Flink codebase. We recommend IntelliJ IDEA for developing projects that involve Scala code.

Minimal requirements for an IDE are:

  • Support for Java and Scala (also mixed projects)
  • Support for Maven with Java and Scala

IntelliJ IDEA

The IntelliJ IDE supports Maven out of the box and offers a plugin for Scala development.

Check out our Setting up IntelliJ guide for details.
