stack commented on HBASE-14921:
-------------------------------
I still don't get this sentence from the diagram attachment:
"The reference to the Cell object is inserted into the ConcurrentSkipListMap.
The reference is just a machine word and thus occupies less memory than the
Cell Object."
What is the machine word? There is the 3 * int that is used to find chunk,
offset and length.. is the 'word' the chunk+offset portion? What CSLM are we
referring to? The MemStore? Or this 'CellBock'? Thanks.
