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

             Summary: ManagedState use case- Add a deduper to Malhar which is backed by ManagedState
                 Key: APEXMALHAR-2035
                 URL: https://issues.apache.org/jira/browse/APEXMALHAR-2035
             Project: Apache Apex Malhar
          Issue Type: New Feature
            Reporter: Chandni Singh
            Assignee: Chandni Singh


Managed State is added to Malhar which handles incremental checkpointing of key/value state. This can be used to create a de-duplicator in Malhar library. 

The de-duper may receive events out of order and if the event is still relevant (not older than configured time) it should find out if the event has been seen before.
