**CopyQueueLength**: This is a number of database "*transaction logs*" that have taken place since a replica database stopped getting updates. This is the queue of all database transactions that are being copied from the production (mounted) database to replica databases. This data is not immediately written to the replica database(s).
**CopyReplayLength**: This represents the queue of all data that was successfully copied from the production database to the replica database on the given DAG member that still needs to process on the replica database. The "**CopyQueueLength**" will need to reach zero before the "**CopyReplayLength**" will start dropping.
**CopyReplayLength**: This represents the queue of all data that was successfully copied from the production database to the replica database on the given DAG member that still needs to process on the replica database. The "**CopyQueueLength**" will need to reach zero before the "**CopyReplayLength**" will start making meaningful progress to reaching zero.
When both the "**CopyQueueLength**" and "**CopyReplayLength**" queues have reached zero, the replica database(s) will have reached 100% parity with the production (active/mounted) database.
