Abstract
Methods for modeling performance of tiered storage of a data processing service given an increase in the storage capacity of a warm storage tier of the tiered storage are disclosed. Buffers in the warm storage tier are used to store data block identifiers corresponding to a set of data blocks that would be stored in the warm storage tier given the increase in storage capacity in addition to those already stored in the warm storage tier. When an incoming query targets a data block that has a corresponding data block identifier in one of the buffers, a hit counter is incremented in order to track the hit rate that would be made on the up-sized warm storage tier. In response to adding the data block targeted by the query to the warm storage tier, one or more evictions from the warm storage tier may additionally be triggered.
