Matthias J. Sax resolved KAFKA-10500. ------------------------------------- Fix Version/s: 2.8.0 Resolution: Fixed > Add API to Start and Stop Stream Threads > ---------------------------------------- > > Key: KAFKA-10500 > URL: https://issues.apache.org/jira/browse/KAFKA-10500 > Project: Kafka > Issue Type: New Feature > Components: streams > Reporter: Bruno Cadonna > Assignee: Walker Carlson > Priority: Major > Labels: kip > Fix For: 2.8.0 > > > Currently, there is no possibility in Kafka Streams to increase or decrease > the number of stream threads after the Kafka Streams client has been started. > Uncaught exceptions thrown in a stream thread kill the stream thread leaving > the Kafka Streams client with less stream threads for processing than when > the client was started. The only way to replace the killed stream thread is > to restart the whole Kafka Streams client. For transient errors, it might > make sense to replace a killed stream thread with a new one while users try > to find the root cause of the error. That could be accomplished by starting a > new stream thread in the uncaught exception handler of the killed stream > thread. > Part of KIP-663 > [https://cwiki.apache.org/confluence/display/KAFKA/KIP-663%3A+API+to+Start+and+Shut+Down+Stream+Threads] > -- This message was sent by Atlassian Jira (v8.3.4#803005)
