-------------------------------------
Summary: Build means to set min/max timestamp on store files on
region splits.
Key: PHOENIX-2307
URL: https://issues.apache.org/jira/browse/PHOENIX-2307
Project: Phoenix
Issue Type: Improvement
Reporter: Samarth Jain
As part of the work done in PHOENIX-914, we noticed that because of region
splits, the time range information cannot be used to filter out the child
regions. When splitting a region HBase (understandably) doesn't read every row
of the region being split and so it doesn't know the min and max timestamps to
add as metadata on the newly created store files.
There possibly could be cases where Phoenix would be able to set the min/ma x
timestamps itself. One such scenario being when the part of row key prior to
the timestamp hasn't changed in the region that is to be split. We would need
HBase APIs to set the min/max timestamp which could be then called in the
coprocessor hook for splits.
