Apurva Mehta updated KAFKA-5270: -------------------------------- Priority: Blocker (was: Major) > 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 > Components: clients, core, producer > Reporter: Apurva Mehta > Priority: Blocker > Labels: exactly-once > Fix For: 0.11.0.0 > > > 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. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
