Anoop Sam John commented on HBASE-18010:
----------------------------------------
{code}
protected long heapSizeChange(Cell cell, boolean succ) {
if (succ) {
return ClassSize
.align(ClassSize.CONCURRENT_SKIPLISTMAP_ENTRY +
CellUtil.estimatedHeapSizeOf(cell));
}
return 0;
}
{code}
{code}
public static long estimatedHeapSizeOf(final Cell cell) {
if (cell instanceof HeapSize) {
return ((HeapSize) cell).heapSize();
}
// TODO: Add sizing of references that hold the row, family, etc., arrays.
return estimatedSerializedSizeOf(cell);
}
{code}
Every ExtendedCell is a HeapSize impl. So we will end up calling KV.heapSize()
only

> The CellChunkMap helps to create a new type of ImmutableSegment, where the
> index (CellSet's delegatee) is going to be CellChunkMap. No big cells or
> upserted cells are going to be supported here.
