Research direction

Start with JIRA HUDI-5666 and the MDT compaction design; the issue does not name an implementation file, test, or entry point. Define how a custom strategy should identify the "files" partition and how its frequency differs from other partitions. Done means the strategy is implemented, documented, and covered by tests for aggressive compaction of that partition.
