Abstract
In at least one embodiment, processing can include: receiving metadata updates for MD pages; recording the MD updates for the MD pages in a MD log; and performing a first destaging phase that writes the MD updates from the MD log to a tablet stored on non-volatile storage. The tablet can include a bucket area and an extension area. The bucket area can include buckets each of which is a predetermined bucket size. The first destaging phase can include: writing a portion of the MD updates from the MD log to the bucket area; and writing a second portion of the MD updates from the MD log to the extension area. Each MD update of the second portion can overflow a corresponding one of the buckets which is included in the bucket area and which is associated with one of the MD pages updated by the MD update.
