James Taylor commented on PHOENIX-3649:
---------------------------------------

Thanks for the patch, [~an...@apache.org]. So the upserts run on the 
server-side are using the query compilation timestamp, right? There is a race 
condition in the original code, so perhaps we're just losing the race now when 
the upsert select is run server-side.

I can't think of a better solution for non transactional tables than yours. The 
only problem is that the index will be active, but it won't be consistent with 
the data table until the buildIndex you added is complete. Perhaps we should 
mark the index as inactive while the buildIndex is running?

> After PHOENIX-3271 higher memory consumption on RS leading to OOM/abort on 
> immutable index creation with multiple regions on single RS
