Abstract
A method for use in a storage system, comprising: placing a write request in an aging queue; waiting until an age of the write request greater than an aging time associated with the aging queue; removing the write request from the aging queue and updating an ordered data structure to include an object that references the write request, the object having an object ID that corresponds to an address that is associated with the write request; retrieving a sequence of object IDs that correspond to objects in the ordered data structure; classifying the sequence into one of at least a sequential pattern category and a random pattern category; generating a hint indicating an outcome of the classification; and setting a duration for which backend (BE) metadata that corresponds to the write request would remain stored in a cache based on the hint.
