Jean-Marc Spaggiari commented on HBASE-13890: --------------------------------------------- {quote} Always check a result of an operation - call regular operation if result is empty or partial. {quote} But this will require an extra RPC call. Is it not possible to have something like MEMSTORE_ONLY_ATTRIBUTE_ELSE_NORMAL where if you have something in the memstore you return, and if not you do a "normal" operation without having to go back to the client? > Get/Scan from MemStore only (Client API) > ---------------------------------------- > > Key: HBASE-13890 > URL: https://issues.apache.org/jira/browse/HBASE-13890 > Project: HBase > Issue Type: New Feature > Components: API, Client, Scanners > Reporter: Vladimir Rodionov > Assignee: Vladimir Rodionov > Attachments: HBASE-13890-v1.patch > > > This is short-circuit read for get/scan when recent data (version) of a cell > can be found only in MemStore (with very high probability). > Good examples are: Atomic counters and appends. This feature will allow to > bypass completely store file scanners and improve performance and latency. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
