Nick Dimiduk commented on HBASE-11331:
--------------------------------------
bq. Any chance of our fixing compressor reuse.
I'll look into it. If anything, it'll be a separate ticket.
bq. I'm game to rerun test when you say its ready.
Hold off on rerunning until I verify/refute my hypothesis on the blockcache
heapsize stuff.
bq. Nice graphs
Awe shucks, thanks boss. This is Grafana running on top of OpenTSDB. No
offense, but I find it nicer to use these dashboards than the gnuplot stuff we
get otherwise. I'm still learning it, but I'll attach the dashboard json file I
used to make the latest figures.

> 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.
