Matthias J. Sax commented on KAFKA-8828: ---------------------------------------- Can you elaborate? Since 2.3, `GlobalKTable` use timestamped stores. However, manually added global stores should not be affected. However, if you add a `GlobalKTable` you don't need to write any code and you would never need to access the `ProcessorContext`. What are you exactly trying to do? The change of [https://cwiki.apache.org/confluence/display/KAFKA/KIP-258%3A+Allow+to+Store+Record+Timestamps+in+RocksDB] should be backward compatible. > [BC Break] Global store returns a TimestampedKeyValueStore in 2.3 > ----------------------------------------------------------------- > > Key: KAFKA-8828 > URL: https://issues.apache.org/jira/browse/KAFKA-8828 > Project: Kafka > Issue Type: Bug > Components: streams > Affects Versions: 2.3.0 > Reporter: Marcos Passos > Priority: Major > > Since 2.3, {{ProcessorContext}} returns a {{TimestampedKeyValueStore}} for > global stores, which is backward incompatible. This change makes the upgrade > path a lot painful and involves creating a non-trivial adapter to hide the > timestamp-related functionality in cases where it is not needed. -- This message was sent by Atlassian Jira (v8.3.2#803003)
