Deprecated Java 8 and Scala 2.12! Apache Kafka 3.0.0 is online

Apache Kafka is a distributed streaming media platform that can handle large amounts of data and enables you to pass messages from one endpoint to another. It has high performance, persistence, multi-copy backup, and horizontal expansion capabilities.

On Tuesday, Apache officially announced that Apache Kafka 3.0.0 was officially launched. This version has updated many important contents, including:

regular changes:

• KIP-750 (Part One): Deprecation of Java 8 support in Kafka
• KIP-751 (Part One): Deprecation of Scala 2.12 support in Kafka
