Abstract
A working-set structure is used to organize cached data for storing to persistent storage, which includes leaf structures and page descriptors (PDs) for data pages to be persisted. Upon adding a new PD located in an address range of an existing leaf structure, a PD population count of the existing leaf structure is compared to a predetermined PD population threshold. When the count is below the threshold, the new PD is incorporated into an existing set of PDs for the existing leaf structure, and otherwise (a) a new leaf structure is created, and (b) the new leaf structure is used for the new PD and later-added PDs in the address range. Flush parallelism is enhanced by avoiding large differences in PD population across a set of leaf structures.
