Anoop Sam John commented on HBASE-14921:
----------------------------------------
Ya on using the chunk from MSLAB for storing the meta data (2 ints) am also
not totally against it. Ya it has its own adv. On demand on heap byte[] if we
used, ya if smaller cells, we will have more such and so more meta data. Also
considering the fact that this compacted in memory CellBlock may last some
time, it is not really short lived object and in most chance get promoted to
old space also. So on demand creation may cause more GC issues (Considering
CMS here).. So MSLAB chunk make all sense.. Only worry was large cells. Ya let
us test more here.
