> By default Memstore uses MSLAB. For each of the Cell added to memstore, we
> will allocate area in MSLAB and return the area in BR wrapper. So each time a
> new BR object is created. Instead of this we can have ThreadLocal level BR
> instance and each time when allocate() API return the BR, we can set the
> byte[], offset, length on this ThreadLocal level BR instance. So totally only
> those many objects as the threads count (max handler count)
