> 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.
