---------------------------------
Assignee: chenfengLiu
> reduce the shuffle work when we just insert but not update and delete
> ---------------------------------------------------------------------
>
> Key: HUDI-4350
> URL: https://issues.apache.org/jira/browse/HUDI-4350
> Project: Apache Hudi
> Issue Type: Improvement
> Components: flink
> Reporter: chenfengLiu
> Assignee: chenfengLiu
> Priority: Major
>
> As the discussion on the https://issues.apache.org/jira/browse/HUDI-4338,
> more shuffle work will cause the network overhead and the risk of the data
> skew.
> So when we build the flink data stream to write to hudi, the orignal plan is
> able to improve this point.
> Now if we wanna update or delete record, we need to load index first, then
> send the index record and the hoodie record to Bucket Assgin Operator.
> Bucket Assin Opeator will build the index state for assgining the bucket for
> incomming record.
> If we just insert the new record not update or delete, we don't need these
> works like buld the index, repartion the existed record.
