Abstract
A technique for managing reference-count decrements (decrefs) includes defining an aggregation domain that includes multiple tablets created at respective points in time, each of the tablets containing multiple sorted buckets arranged in a respective sequence of bucket identifiers that is repeated across all of the tablets, the sorted buckets containing decrefs for respective sets of metadata pages. The technique further includes assigning a decref job to a specified set of bucket identifiers and destaging, by the decref job, multiple decrefs from the tablets to persistent metadata pages, beginning with decrefs in buckets having the specified set of bucket identifiers and proceeding until a target number of decrefs has been destaged.
