[jira] [Created] (KAFKA-3133) Add putIfAbsent function to KeyValueStore

Guozhang Wang created KAFKA-3133:
------------------------------------

             Summary: Add putIfAbsent function to KeyValueStore
                 Key: KAFKA-3133
                 URL: https://issues.apache.org/jira/browse/KAFKA-3133
             Project: Kafka
          Issue Type: Sub-task
            Reporter: Guozhang Wang


Since a local store will only be accessed by a single stream thread, there is no atomicity concerns and hence this API should be easy to add.
