[jira] [Updated] (PHOENIX-1683) Support HBase HA
Query(timeline-consistent region replica read)
[ https://issues.apache.org/jira/browse/PHOENIX-1683?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jeffrey Zhong updated PHOENIX-1683:
-----------------------------------
Description:
As HBASE-10070 is in HBase1.0, we could leverage this feature by providing a new consistency level TIMELINE.
Assumption: A user has already enabled a hbase table for timeline consistency
In the connection property or by "ALTER SESSION SET CONSISTENCY_LEVEL=TIMELINE" statement, we could set current connection/session consistency level to "TIMELINE" to take the advantage of TIMELINE read.
