Introducing Apache Kafka 3.5

Escrito por

We are proud to announce the release of Apache Kafka® 3.5.0. This release contains many new features and improvements. This blog post will highlight some of the more prominent features. For a full list of changes, be sure to check the release notes.

See the Upgrading to 3.5.0 from any version 0.8.x through 3.4.x section in the documentation for the list of notable changes and detailed upgrade steps.

The ability to migrate Kafka clusters from ZK to KRaft mode with no downtime is still an early access feature. It is currently only suitable for testing in non-production environments. See KIP-866 for more details.

Note: ZooKeeper is now marked deprecated in this release. ZooKeeper is planned to be removed in Apache Kafka 4.0. (see ZooKeeper Deprecation)

Kafka Broker, Controller, Producer, Consumer and Admin Client

KIP-881: Rack-aware Partition Assignment for Kafka Consumers: Kafka 3.4.0 only contained the protocol changes for KIP-881. The built-in assignors have now been updated to support rack awareness.

KIP-887: Add ConfigProvider to make use of environment variables: KIP-887 introduces a new ConfigProvider implementation, EnvVarConfigProvider to retrieve configurations from environment variables.

KIP-900: KRaft kafka-storage.sh API additions to support SCRAM for Kafka Brokers: KIP-900 updates the kafka-storage tool and adds a mechanism to configure SCRAM for inter-broker authentication with KRaft.

KIP-903: Replicas with stale broker epoch should not be allowed to join the ISR: KIP-903 addresses a limitation of the inter-broker replication protocol which could lead to data loss in case of a broker failing while another broker had an unclean shutdown.

Kafka Streams

KIP-399: Extend ProductionExceptionHandler to cover serialization exceptions: KIP-399 adds a method, handleSerializationException(), to the ProductionExceptionHandler interface to handle any serialization errors encountered while producing records.

KIP-889: Versioned State Stores: KIP-889 introduces versioned state stores to improve the accuracy of joins when out of order records are processed.

KIP-907: Add Boolean Serde to public interface: Kafka Streams includes built-in Serdes for most primitive types. KIP-907 adds a new one for booleans.

Kafka Connect

KIP-710: Full support for distributed mode in dedicated MirrorMaker 2.0 clusters: KIP-710 improves the dedicated mode of MirrorMaker. It now supports running multiple instances and handling automatic reconfigurations.

KIP-875: First-class offsets support in Kafka Connect: KIP-875 adds REST API endpoints for managing offset of Connectors. 3.5.0 only contains endpoints for listing offsets. Endpoints for updating and deleting offsets will come in a future release.

KIP-894: Use incrementalAlterConfig for syncing topic configurations: With KIP-894, MirrorMaker can use the IncrementalAlterConfig API when mirroring topic configuration between clusters.

KAFKA-14021: MirrorMaker 2 should implement KIP-618 APIs: KAFKA-14021 adds support for exactly-once semantics to MirrorSourceConnector.
