Abstract
A technique is directed to processing metadata changes. The technique involves designating a first tablet to ingest metadata changes and a second tablet to destage previously ingested metadata changes, the first tablet being partitioned into a first reserved space and a first regular space that form a first memory pool, and the second tablet being partitioned into a second reserved space and a second regular space that form a second memory pool. The technique further involves, while the first tablet is designated to ingest metadata changes and the second tablet is designated to destage previously ingested metadata changes, ingesting metadata changes into the first tablet and destaging the previously ingested metadata changes from the second tablet. The technique further involves, when the first tablet becomes full, performing a switch operation that designates the second tablet to ingest metadata changes and the first tablet to destage previously ingested metadata changes.
