[GitHub] [spark] HyukjinKwon commented on pull request #36683: [SPARK-39301][SQL][PYTHON] Leverage LocalRelation in createDataFrame with Arrow optimization

HyukjinKwon commented on PR #36683:
URL: https://github.com/apache/spark/pull/36683#issuecomment-1143230871

   This PR is ready for a look now. TL;DR:
   - I added one new configuration `spark.sql.execution.arrow.localRelationThreshold` as a threshold.
   - I fixed the code path to respect `spark.sql.execution.arrow.maxRecordsPerBatch` when creating Arrow batches to avoid forcing users to set a larger `spark.rpc.message.maxSize`.
