Serhiy Bilousov commented on PHOENIX-1580:
------------------------------------------
I am waiting with inpatients to try this out. We have good case for it to turn
table around wide->tall. I have early question:
1. If lets say I have statement with 23 UNIONS will thouse be executed in
parallel?
2. If all of my UNIONS just take different columns from same CF and key (or
keys base on where part) will I have one get from hbase and all wide->tall will
happens on PHOENIX side ?
Thank you
