re: "my first version is using 20,000 Get²
Just throwing this out there, but have you looked at multi-get? Multi-get
will group the gets by RegionServer internally.
You are doing a lot of IO for a web-app so this is going to be tough to
make ³fast², but there are ways to make it ³faster.²
But since you only have 1,000,000 rows you might not have many regions, so
this might wind up all going on the same RegionServer.
