>
> Key: HUDI-5012
> URL: https://issues.apache.org/jira/browse/HUDI-5012
> Project: Apache Hudi
> Issue Type: Improvement
> Components: cleaning
> Reporter: sivabalan narayanan
> Assignee: sivabalan narayanan
> Priority: Critical
> Fix For: 0.12.1
>
>
> Within clean planning phase, we do a map() for every partition and then trigger planning for each partition within that.
>
> For very large number of partitions, and if cleaner shuffle parallelism is small, this results in more sequential planning. We can enhance this with mapPartitions call and optimize it
