Jeffrey Zhong updated PHOENIX-1683:
-----------------------------------
Attachment: PHOENIX-1683.patch
A user can turn on TIMELINE read by two ways:(assuming the related table has
enabled region replica already)
1) Through JDBC url string: Append ";Consistency=TIMELINE" into URL string
2) alter session set Consistency = 'timeline'
Using alter session set Consistency = 'strong' to turn timeline read off.
When a user uses explain command, "TIMELINE-CONSISTENCY" will be in the plan
output when timeline consistency is enabled.
> Support HBase HA Query(timeline-consistent region replica read)

> 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.
