ramkrishna.s.vasudevan commented on PHOENIX-1402:
-------------------------------------------------
Ya possible. Need to compare the guideposts (the rowkeys with the region's
start and end keys) with the new daughter region's start and end key. Add a new
entry to the stats table after splitting the guideposts with the new daughter
regions.
But still these would be done in the postSplit hooks only I suppose.

> Rather than scan the new regions on a split (which is potentially expensive,
> and might be causing the timeouts you're seeing [~jfernando_sfdc]), we should
> instead just split up the existing guideposts between new two new regions
> based on the split point.
