[jira] [Created] (KAFKA-6621) Update Streams docs with details for UncaughtExceptionHandler

Matthias J. Sax created KAFKA-6621:
--------------------------------------

             Summary: Update Streams docs with details for UncaughtExceptionHandler
                 Key: KAFKA-6621
                 URL: https://issues.apache.org/jira/browse/KAFKA-6621
             Project: Kafka
          Issue Type: Improvement
          Components: documentation, streams
            Reporter: Matthias J. Sax


We should update the docs to explain that calling {{KafkaStreams#close()}} within the UncaughtExceptionHandler-callback might result in a deadlock and one should always specify a timeout parameter for this case.

As an alternative to avoid the deadlock, setting a flag in the handler and calling {{#close}} outside of the callback should also work.
