示例1: heapSize
/**
* HeapSize implementation
*
* We do not count the bytes in the rowCache because it should be empty for a KeyValue in the
* MemStore.
*/
@Override
public long heapSize() {
int sum = 0;
sum += ClassSize.OBJECT;// the KeyValue object itself
sum += ClassSize.REFERENCE;// pointer to "bytes"
sum += ClassSize.align(ClassSize.ARRAY);// "bytes"
sum += ClassSize.align(length);// number of bytes of data in the "bytes" array
sum += 2 * Bytes.SIZEOF_INT;// offset, length
sum += Bytes.SIZEOF_LONG;// memstoreTS
return ClassSize.align(sum);
}
示例2: heapSize
@Override
public long heapSize() {
long sum = CellUtil.estimatedHeapSizeOf(cell) - cell.getTagsLength();
sum += ClassSize.OBJECT;// this object itself
sum += (2 * ClassSize.REFERENCE);// pointers to cell and tags array
if (this.tags != null) {
sum += ClassSize.align(ClassSize.ARRAY);// "tags"
sum += this.tags.length;
}
return sum;
}
示例3: heapSizeWithoutTags
/**
* This is a hack that should be removed once we don't care about matching
* up client- and server-side estimations of cell size. It needed to be
* backwards compatible with estimations done by older clients. We need to
* pretend that tags never exist and KeyValues aren't serialized with tag
* length included. See HBASE-13262 and HBASE-13303
*/
