             Summary: Reduce stream task migrations and initialization costs
                 Key: KAFKA-2763
                 URL: https://issues.apache.org/jira/browse/KAFKA-2763
             Project: Kafka
          Issue Type: Sub-task
          Components: kafka streams
    Affects Versions: 0.9.0.0
            Reporter: Yasuhiro Matsuda


Stream task assignment is not aware of either the previous task assignment or 
local states of participating clients. By making the assignment logic aware of 
them, we can reduce task migrations and initialization cost.
