stack commented on HBASE-15016: ------------------------------- Let me have a go at it... will be back.. [~eshcar] > StoreServices facility in Region > -------------------------------- > > Key: HBASE-15016 > URL: https://issues.apache.org/jira/browse/HBASE-15016 > Project: HBase > Issue Type: Sub-task > Reporter: Eshcar Hillel > Assignee: Eshcar Hillel > Attachments: HBASE-15016-V01.patch, HBASE-15016-V02.patch, > HBASE-15016-V03.patch, Regioncounters.pdf, suggestion.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
