  16. val fileCleanupDelayMs: Long

    If we delete the old files after compaction at once, there is a race condition in S3: other processes may see the old files are deleted but still cannot see the compaction file using "list".

    If we delete the old files after compaction at once, there is a race condition in S3: other processes may see the old files are deleted but still cannot see the compaction file using "list". The allFiles handles this by looking for the next compaction file directly, however, a live lock may happen if the compaction happens too frequently: one processing keeps deleting old files while another one keeps retrying. Setting a reasonable cleanup delay could avoid it.

    CompactibleFileStreamLog maintains logs by itself, and manual purging might break internal state, specifically which latest compaction batch is purged.
