stack commented on HBASE-953:
-----------------------------
Rong-en: I'm looking to enable BLOCKCACHE in HColumnDescriptor as the default.
Currently its off. The size I'm playing with is this one:
hbase.hstore.blockCache.blockSize
I ran with 1.6.0_10 JDK and 16k blocksize and all single-client runs ran as
well as an overnight 16 concurrent client test. All passed. Running some more
tests to see if I can make an OOME happen.
> Reevaluate HBASE-288 block caching work; should it be enabled always?

> Go back and take another look at the Tom White work. We've gotten boost in
> writing and scanning because of J-D work. HBASE-288 looks like it boosts
> sequential reads and perhaps random read a little. Take another look.
