Bill, we discovered a regression bug in Kafka Streams last Friday that was introduced in the 2.6.0 release. It affects EOS users, what is a growing percentage of Kafka Streams users.
The PR is already merged to `trunk` and `2.6` branch: https://issues.apache.org/jira/browse/KAFKA-10755 We also consider it a blocker for `2.6.1` and cut a new RC. Thus, we should also consider it a blocker for `2.7.0`. Let me know what you think. If you agree, I can cherry-pick the fix to 2.7 branch. -Matthias On 11/19/20 9:09 AM, Bill Bejeck wrote: > Hello Kafka users, developers, and client-developers, > > This is the third candidate for the release of Apache Kafka 2.7.0. > > This is a major release that includes many new features, including: > > * Configurable TCP connection timeout and improve the initial metadata fetch > * Enforce broker-wide and per-listener connection creation rate (KIP-612, > part 1) > * Throttle Create Topic, Create Partition and Delete Topic Operations > * Add TRACE-level end-to-end latency metrics to Streams > * Add Broker-side SCRAM Config API > * Support PEM format for SSL certificates and private key > * Add RocksDB Memory Consumption to RocksDB Metrics > * Add Sliding-Window support for Aggregations > > This release also includes a few other features, 53 improvements, and 84 > bug fixes. > > Release notes for the 2.7.0 release: > https://home.apache.org/~bbejeck/kafka-2.7.0-rc2/RELEASE_NOTES.html > > *** Please download, test, and vote *by Wednesday, November 25, 12 pm* ET > > Kafka's KEYS file containing PGP keys we use to sign the release: > https://kafka.apache.org/KEYS > > * Release artifacts to be voted upon (source and binary): > https://home.apache.org/~bbejeck/kafka-2.7.0-rc2/ > > * Maven artifacts to be voted upon: > https://repository.apache.org/content/groups/staging/org/apache/kafka/ > > * Javadoc: > https://home.apache.org/~bbejeck/kafka-2.7.0-rc2/javadoc/ > > * Tag to be voted upon (off 2.7 branch) is the 2.7.0 tag: > https://github.com/apache/kafka/releases/tag/2.7.0-rc2 > > * Documentation: > https://kafka.apache.org/27/documentation.html > > * Protocol: > https://kafka.apache.org/27/protocol.html > > * Successful Jenkins builds for the 2.7 branch: > Unit/integration tests: > https://ci-builds.apache.org/blue/organizations/jenkins/Kafka%2Fkafka-2.7-jdk8/detail/kafka-2.7-jdk8/57/ > System tests: (link to follow) > > Thanks, > Bill >
