stack commented on HBASE-17204:
-------------------------------
Moved it out to 2.0.0 -- our general bucket of 2.0.0 issues that we'll have to
sort through one of these days to figure 2.1 and 3.0.0 -- after discussion w/
[~ram_krish] and [~anoop.hbase]; we need more time than is available readying
this for hbase-2 (and it has to be right if we don't want to piss of our
users). Thanks lads.

> L2 cache can be used for data blocks. By default it is off now. After
> HBASE-11425 work, L2 off heap cache can equally perform with L1 on heap
> cache. On heavy loaded workload, this can even out perform L1 cache. Pls see
> recently published report by Alibaba. Also this work was backported by
> Rocketfuel and similar perf improvement report from them too.
> Let us turn L2 off heap cache ON. As it is off heap, we can have much larger
> sized L2 BC. What should be the default size?
