> We ran into some situations when the compaction was marked as finished and
> was in ready for cleaning state, but the compaction txn was still open. This
> inconsistency led to data loss. There were some improvements in the cleaner
> to avoid these situations, but we should consider checking the txn state when
> the cleaner selects a compaction to clean.
