Returns a new db instance with all datoms <= tx-num removed from the overlay.
safe-advance-dbclj
(safe-advance-db db entry)Given a transaction log entry, advances the database to a state where the (already validated) tx has been applied. Requires non-speculative log entries. If the log-entry indicates that the indexes have flushed, will (re)load the database state with the new indexes from the backing store.
