JingsongLi opened a new issue, #749:
URL: https://github.com/apache/incubator-paimon/issues/749

   ### Search before asking
   
   - [X] I searched in the [issues](https://github.com/apache/incubator-paimon/issues) and found nothing similar.
   
   
   ### Motivation
   
   By default, batch sink should sort the input by partition and sequence_field to avoid generating a large number of small files. Too many small files cause poor performance, especially object storage.
   
   We can not implement `SupportsPartitioning.requiresPartitionGrouping`. we need sequence.field to sort, otherwise we can't confirm what the last record is.
   
   ### Solution
   
   _No response_
   
   ### Anything else?
   
   _No response_
   
   ### Are you willing to submit a PR?
   
   - [ ] I'm willing to submit a PR!
