> I created this issue to be the overall issue for threading to increase read and write
performance in HBase and to keep it as a discussion place about threading of these elements
in general. Today we are doing batching of  writes and from 0.20 you will be able to do that
for reads too. The thing is that the batching procedure doesn't use the ability to run these
different queries at the same time, but more like a series of queries. I think that after
getting a good stable 0.20 system down we should try to add threading to increase throughput
for both reading and writing. At the top level of these calls I don't think that is is goin
gto be to hard to do this in parallel, where it gets a little bit more complicated is when
you get down to running a get query on memcache and all the storefiles at the same time, but
above that I don't see it being to hard. I do think that this should not be a part of 0.20
but rather an optimization in 0.21 or so.
