Abstract
A technique of managing metadata includes receiving metadata changes into active tablets. When the active tablets are filled, the active tablets are changed to frozen tablets, whereupon previously frozen tablets are freed and changed to the active tablets. The technique further includes destaging metadata changes from the frozen tablets to pages in backend storage under read locks. Tablet generation identifiers (TGIDs) are assigned to successive generations of tablets, and a TGID of the frozen tablets is stored with the pages that are written as part of destaging from the frozen tablets.
