stack commented on HBASE-11331:
-------------------------------
Any chance of our fixing compressor reuse. As you say, I'd imagine it'd mess up
any possibility of nice numbers when this feature enabled. I'm game to rerun
test when you say its ready. That a fancy graph tool on front a tsdb?
[~ndimiduk]? Nice graphs.

> Maintaining data in its compressed form in the block cache will greatly
> increase our effective blockcache size and should show a meaning improvement
> in cache hit rates in well designed applications. The idea here is to lazily
> decompress/decrypt blocks when they're consumed, rather than as soon as
> they're pulled off of disk.
> This is related to but less invasive than HBASE-8894.
