The Restream Queue is your safety net for ensuring zero data loss. The Restream Queue collects all the events that were not loaded to your target database, for whichever reason, making them easy to fix and enabling you to “restream” them into your target database.
Each event remains in the Restream Queue until:
You address the error which resulted in it being there.
You restream them to your target database.
The event is successfully loaded to your target database.
