### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) ### Search before asking - [X] I have searched in the [issues](https://github.com/apache/kyuubi/issues?q=is%3Aissue) and found no similar issues. ### What would you like to be improved? when merging small files(set `spark.sql.optimizer.insertRepartitionBeforeWrite.enabled`=true) , the default session advisory partition size (64MB) will be used as target. This default value can still lead to small files because the written data can be compressed nicely using columnar file formats (usually 1/4 or smaller of the shuffle exchange size, the result is often around 15MB). Spark now support configuring the rebalance expression advisory size in https://github.com/apache/spark/pull/40421 . So we can have a configuration that can configure the merge size separately. ### How should we improve? add one configuration to control the size separately ### Are you willing to submit PR? - [X] Yes. I would be willing to submit a PR with guidance from the Kyuubi community to improve. - [ ] No. I cannot submit a PR at this time. -- This is an automated message from the Apache Git Service.
