Bruno Cadonna updated KAFKA-10500: ---------------------------------- Labels: needs-kip (was: ) > Add API to Start and Stop Stream Threads > ---------------------------------------- > > Key: KAFKA-10500 > URL: https://issues.apache.org/jira/browse/KAFKA-10500 > Project: Kafka > Issue Type: Sub-task > Components: streams > Reporter: Bruno Cadonna > Priority: Major > Labels: needs-kip > > 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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
