Description
The default implementation of a memstore ensures that between two flushes the memstore size increases monotonically. Supporting new memstores that store data in different formats (specifically, compressed), or that allows to eliminate data redundancies in memory (e.g., via compaction), means that the size of the data stored in memory can decrease even between two flushes. This requires memstores to have access to facilities that manipulate region counters and synchronization.
This subtasks introduces a new region interface – StoreServices, through which store components can access these facilities.
