Anastasia Braginsky commented on HBASE-14921:
---------------------------------------------
bq. Are there methods from ConcurrentNM that we use from delegatee? Or are we
just doing NM methods? Wondering if we could change it so delegatee was just a
NM.
I think that the main reason why delegatee is ConcurrentNM is that CSLM is
ConcurrentNM. CSLM is indeed concurrent.
bq. Would a large Cell break our nice 3 int addressing scheme or this very
large cell chunk will turn a few somersaults to make the stuff fit?
The last option. The addressing scheme remains 3 int, but very-large are
special big chunks allocated for special size.
