> MIN_HISTORY_LEVEL table is used in two places:
> * Cleaner uses it to decide if the files can be removed - this could be
> replaced by adding a new column to compaction_queue storing the next_txn_id
> when the change was committed, and before cleaning checking the minimum open
> transaction id in the TXNS table
> * Initiator uses it to decide if some items from TXN_TO_WRITE_ID table can
> be removed. This could be replaced by using the WRITE_SET.WS_COMMIT_ID.
