Subject [jira] [Created] (KAFKA-5270) TransactionManager should send and `AddOffsetsToTxn` request only once per group per transaction
Date Wed, 17 May 2017 22:42:04 GMT
Apurva Mehta created KAFKA-5270:
-----------------------------------

             Summary: TransactionManager should send and `AddOffsetsToTxn` request only once
per group per transaction
                 Key: KAFKA-5270
                 URL: https://issues.apache.org/jira/browse/KAFKA-5270
             Project: Kafka
          Issue Type: Sub-task
            Reporter: Apurva Mehta


Currently, we send the `AddOffsetsToTxn` request unconditionally every time, even if we receive
multiple sendOffsets for the same group. We could keep track of the added groups in the TransactionManager
and not resend this RPC multiple times for the same transaction as the subsequent instances
add no new information.
