James Taylor commented on PHOENIX-2307:
---------------------------------------

[~lhofhansl] - are there APIs we could use from a split coprocessor hook to set the min/max timestamp for an HFile?

> On region splits, there possibly could be cases where Phoenix would be able to set the min/max 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. Or when the leading part of the row key is timestamp, with or without salting. In such cases, it would be relatively easy to figure out what the min and max timestamps should be on the newly created child regions. To build this we would need HBase apis to set the min/max timestamps on the HFiles which could be then called in coprocessor hooks for splits.
