Anastasia Braginsky commented on HBASE-18010:
---------------------------------------------
Thank you [~anoop.hbase]! I get what you are saying, but I still need more
guidance to get to the KeyValue.heapSize(). I am looking on
estimatedSerializedSizeOf:
{code}
public static int estimatedSerializedSizeOf(final Cell cell) {
if (cell instanceof ExtendedCell) {
return ((ExtendedCell) cell).getSerializedSize(true) + Bytes.SIZEOF_INT;
}
return getSumOfCellElementLengths(cell) +
// Use the KeyValue's infrastructure size presuming that another
implementation would have
// same basic cost.
KeyValue.ROW_LENGTH_SIZE + KeyValue.FAMILY_LENGTH_SIZE +
// Serialization is probably preceded by a length (it is in the
KeyValueCodec at least).
Bytes.SIZEOF_INT;
}
{code}
I assume we are talking about ExtendedCell so looking on getSerializedSize (of
KeyValue). By the way why integer is added there, near getSerializedSize?
{code}
public int getSerializedSize(boolean withTags) {
if (withTags) {
return this.length;
}
return this.getKeyLength() + this.getValueLength() +
KEYVALUE_INFRASTRUCTURE_SIZE;
}
{code}
So I do not see KeyValue.heapSize() yet...

> 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.
