This PR propose to add DataFile rewrite Action to Iceberg. The purpose of adding this functionality is to merge the small files into large ones to reduce the FileSystem overhead. This PR uses `read.split.target-size` to control the read size of each task, and uses `write.target-file-size-bytes` to control the write size of each task. It also takes care of table partition to compact the files under each partition (without shuffling). Besides user could specify the `Filter` expressions to only compact the files in some specific partitions. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
