Subject [jira] [Commented] (HBASE-15016) StoreServices facility in Region
Date Wed, 24 Feb 2016 05:50:18 GMT

Anoop Sam John commented on HBASE-15016:
----------------------------------------

bq.//// method for debugging tests
bq.7873	  public void throwException(String title, String regionName) {
Can we keep the scope as package level only?  Such a public method looks bad.

> 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.
