---------------------------------
Summary: Support assigning the same SSP to multiple tasknames
Key: SAMZA-353
URL: https://issues.apache.org/jira/browse/SAMZA-353
Project: Samza
Issue Type: Bug
Components: container
Affects Versions: 0.8.0
Reporter: Jakob Homan
Post SAMZA-123, it is possible to add the same SSP to multiple tasknames,
although currently we check for this and error out if this is done. We should
think through the implications of having the same SSP appear in multiple
tasknames and support this if it makes sense.
This could be used as a broadcast stream that's either added by Samza itself to
each taskname, or individual groupers could do this as makes sense. Right now
the container maintains a map of SSP to TaskInstance and delivers the ssp to
that task instance. With this change, we'd need to change the map to SSP to
Set[TaskInstance] and deliver the message to each TI in the set.
