Subject [jira] [Created] (GEARPUMP-358) Performance regression due to costly watermark calculation
Date Tue, 17 Oct 2017 09:06:00 GMT
Huafeng Wang created GEARPUMP-358:
-------------------------------------

             Summary: Performance regression due to costly watermark calculation
                 Key: GEARPUMP-358
                 URL: https://issues.apache.org/jira/browse/GEARPUMP-358
             Project: Apache Gearpump
          Issue Type: Bug
            Reporter: Huafeng Wang


For example, in streaming example SOL, everytime SOLStreamProducer output a message to downstream,
it will send a Watermark message to itself, which will trigger watermark calculation. We should
avoid flooding Watermark messages.
