Threading writes and reads into HBase.
--------------------------------------
Key: HBASE-1307
URL: https://issues.apache.org/jira/browse/HBASE-1307
Project: Hadoop HBase
Issue Type: Improvement
Components: regionserver
Affects Versions: 0.21.0
Reporter: Erik Holstad
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.
