Re: Scan vs map-reduce

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.
