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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
