    Description

      Copying the CollectionCatalog is expensive. When there are tens of thousands of collections, operations like rollback become substantially slower. When the server is rolling back to the stable timestamp, the global lock is held in exclusive mode. We should be able to avoid making multiple copies of the collection catalog.
