Anoop Sam John commented on HBASE-11206:
----------------------------------------
We can. As Nick pointed above, it works with on heap things only. This is
HeapMemory tuner. So the Memstore (MSLAB) and BC both in on heap. Now we have
off heap support for both these in 2.0. But there is not auto tuner for off
heap. But any way another story and can be done later. This can be helpful
for those who use both on heap.
> Enable automagically tweaking memstore and blockcache sizes

> "Automagically tweak global memstore and block cache sizes based on workload"
> adds a nice new feature. It is off by default. Lets turn it on for 0.99.
> Liang Xie is concerned that automatically shifting blockcache and memstore
> sizes could wreck havoc w/ GC'ing in low-latency serving situation -- a valid
> concern -- but lets enable this feature in 0.99 and see how it does. Can
> always disable it before 1.0 if a problem.
