[jira] [Created] (TEZ-2411) Offload DataMovement event creation from the AM to the tasks

Bikas Saha created TEZ-2411:
-------------------------------

             Summary: Offload DataMovement event creation from the AM to the tasks
                 Key: TEZ-2411
                 URL: https://issues.apache.org/jira/browse/TEZ-2411
             Project: Apache Tez
          Issue Type: Task
            Reporter: Bikas Saha
            Assignee: Bikas Saha


Today the AM creates a new DataMovement event from the original event sent by the producer task and supplements the new event with source/target indices for the consumer task. This new event creation can be offloaded to the task runtime and thus save CPU cycles on the AM for the object creation. Secondly, the original event can be kept in serialized form inside the AM and sent as is to the task over the RPC, thus potentially saving serde CPU for these events in addition to the object creation CPU.
