## Background When an existing table is migrated to the Flink implementation of RewriteDataFiles and its historical data has not been compacted thoroughly,or modify the targetFileSize, the Flink maintenance job must first rewrite the entire table before it can follow the user’s intended schedule. This initial compaction can run for a very long time, while new data cannot trigger compaction, resulting in degraded query performance. ## Purpose This PR introduces an optional filter parameter to Flink’s RewriteDataFiles. Users can define predicates (e.g. data whose time is greater than a given timestamp) so that only the necessary subset of data is compacted, allowing historical data to be skipped. -- This is an automated message from the Apache Git Service.
