Description

https://github.com/apache/hudi/blob/6a0ba2d4e466408d85aa0b22dc32e9581acdb3e3/hudi-flink-datasource/hudi-flink/src/main/java/org/apache/hudi/table/HoodieTableSink.java#L92-L103

I would like to upsert small files first and merge to big file after to increasing both write and read performance.
But Hudi only allow clustering on insert operation of COW table now....

Research direction

Start with the linked hudi-flink-datasource/hudi-flink/src/main/java/org/apache/hudi/table/HoodieTableSink.java lines 92-103 and trace how clustering is currently limited for COW tables. Identify the relevant write-path tests, then define completion as verified support or an explicit decision for clustering after append/upsert operations.
