[jira] [Commented] (HBASE-17836) CellUtil#estimatedSerializedSizeOf is slow when input is ByteBufferCell

    [ https://issues.apache.org/jira/browse/HBASE-17836?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15942332#comment-15942332 ] 

Anoop Sam John commented on HBASE-17836:
----------------------------------------

There is one diff u can note.  There is addition of Bytes.SIZEOF_INT in CellUtil method.  Ya we can fix CellUtil method to check for ExtendedCell

> We call CellUtil#estimatedSerializedSize to calculate the size of rows when scanning. If the input is ByteBufferCell, the CellUtil#estimatedSerializedSizeOf parses many length components to get the qualifierLength stored in the backing buffer.
> We should consider using the KeyValueUtil#getSerializedSize.
