---------------------------------

             Summary: AM should read checkpoints and provide them to containers
                 Key: SAMZA-329
                 URL: https://issues.apache.org/jira/browse/SAMZA-329
             Project: Samza
          Issue Type: Improvement
          Components: kafka
            Reporter: Jakob Homan


Currently each container reads its checkpoint partition to find the latest 
offsets.  Post SAMZA-123, the checkpoints are written into a single-partition 
topic that each container reads through, discarding those checkpoints for which 
it does not have SSPs.  It would be better if the AM were to read the 
checkpoint once and pass the offset to the container as part of the input 
stream definition.
