[FLINK-36209] Remove redundant operations in the initialization of KafkaSourceEnumState (#116)

In certain methods, such as the DynamicKafkaSourceEnumerator#onHandleSubscribedStreamsFetch() method, partitions are divided into assignedPartitions and unassignedInitialPartitions before being passed as parameters to the KafkaSourceEnumState constructor. However, within the constructor, these assignedPartitions and unassignedInitialPartitions are recombined into partitions, leading to unnecessary operations and reduced performance. By optimizing the code to pass partitions directly as a parameter when initializing KafkaSourceEnumState, we can eliminate redundant operations and enhance performance.

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.

Documentation

The documentation of Apache Flink is located on the website: https://flink.apache.org or in the docs/ directory of the source code.

Fork and Contribute

This is an active open-source project. We are always open to people who want to use the system or contribute to it. Contact us if you are looking for implementation tasks that fit your skills. This article describes how to contribute to Apache Flink.
