Yes. This PR aiming to selectively tune a large RDD only while keeping the existing behavior in the same ways in small RDDs. Increase `spark.sql.files.maxPartitionBytes` directly has these issues: 1. There are multiple data sources in one SQL, setting `spark.sql.files.maxPartitionBytes` will affect all data sources. 2. We don't know how much `spark.sql.files.maxPartitionBytes` should be set to, sometimes it may be very large(May be more than 20GiB). -- This is an automated message from the Apache Git Service.
