-------------------------------------
Summary: 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
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.
