-------------------------------
Summary: Flush only happens on executor main thread
Key: STORM-3646
URL: https://issues.apache.org/jira/browse/STORM-3646
Project: Apache Storm
Issue Type: Bug
Reporter: Ethan Li
Flush only happens on executor main thread. If topologies have their own
threads within bolts, and when
{code:java}
topology.producer.batch.size
topology.transfer.batch.size
{code}
are larger than 1, some tuples will be batched and possible never be sent to
downstream.
The default value for them is 1. So it is fine when the configs are not
explicitly changed.
