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'?
