that's exactly what I did. first I combined small files using `RewriteDataFilesAction` then I executed `ExpireSnapshotsAction` using a timestamp of a snapshot before the one created by `RewriteDataFilesAction` (i.e. latest) I noticed that only a small number of files got removed. Then I've fond the following statement in docs: ``` in some cases normal snapshot expiration may not be able to determine a file is no longer needed and delete it. ``` And decided to run `RemoveOrphanFilesAction`. Unfortunately, it deleted a lot of files that weren't combined. Also: `It will delete a superset of the files deleted by expire snapshot.` could you please explain ? -- This is an automated message from the Apache Git Service.
