> We can make use of MSLAB pool for this off heap memstore.
> Right now one can specify the global memstore size (heap size) as a % of max
> memory using a config. We will add another config with which one can specify
> the global off heap memstore size. This will be exact size not as %. When off
> heap memstore in use, we will give this entire area for the MSLAB pool and
> that will create off heap chunks. So when cells are added to memstore, the
> cell data gets copied into the off heap MSLAB chunk spaces. Note that when
> the pool size is not really enough and we need additional chunk creation, we
> wont use off heap area for that. We dony want to create so many on demand
> DBBs.
