stack commented on HBASE-14921:
-------------------------------
bq. MemstoreCompactingIterator is an iterator (based on StoreScanner) over the
compaction pipeline segments...
Ok. Missed that. If it is a Scanner, why not call it a Scanner?
CompactingScanner? InMemoryCompactingScanner ...
bq. The plan is to support special very-large variable size Chunks, which are
not going to be reused. In this case we plan to have Chunk per Cell.
Ok. Sounds good. Would they be allocated per use? Perhaps onheap rather than
offheap because then we keep offheap regular and offheap allocations are slow
anyways.
