-----------------------------------
[~jamestaylor]
About joins. I think that the joins query is always a big query almost the
whole table.
about all big query. the small scan has a bad performance. So I set smallScan
false before
> Set scan.setSmall(true) when appropriate

> There's a nice optimization that has been in HBase for a while now to set a
> scan as "small". This prevents extra RPC calls, I believe. We should add a
> hint for queries that forces it to be set/not set, and make our best guess on
> when it should default to true.
