Here is a summary of some notable changes: TLS 1. Here is a summary of some notable changes: Allow consumers to fetch from closest replica. Support for incremental cooperative rebalancing to the consumer rebalance protocol. MirrorMaker 2. New Java authorizer Interface. Support for non-key joining in KTable. Administrative API for replica reassignment. Kafka Connect now supports incremental cooperative rebalancing. Kafka Streams now supports an in-memory session store and window store.
The AdminClient now allows users to determine what operations they are authorized to perform on topics. There is a new broker start time metric. We now track partitions which are under their min ISR count. Consumers can now opt-out of automatic topic creation, even when it is enabled on the broker. Kafka components can now use external configuration stores KIP We have implemented improved replica fetcher behavior when errors are encountered. Here is a summary of some notable changes: Java 11 support Support for Zstandard, which achieves compression comparable to gzip with higher compression and especially decompression speeds KIP Avoid expiring committed offsets for active consumer group KIP Provide Intuitive User Timeouts in The Producer KIP Kafka's replication protocol now supports improved fencing of zombies.
Previously, under certain rare conditions, if a broker became partitioned from Zookeeper but not the rest of the cluster, then the logs of replicated partitions could diverge and cause data loss in the worst case KIP Here is a summary of some notable changes: KIP adds support for prefixed ACLs, simplifying access control management in large secure deployments.
Bulk access to topics, consumer groups or transactional ids with a prefix can now be granted using a single rule. After logging in, click Connect to this cluster on the right, and click the Sample code tab. Copy the snippet from the Sample connection code section into your Kafka client application.
