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

Chia-Ping Tsai created HBASE-17836:
--------------------------------------

             Summary: CellUtil#estimatedSerializedSizeOf is slow when input is ByteBufferCell
                 Key: HBASE-17836
                 URL: https://issues.apache.org/jira/browse/HBASE-17836
             Project: HBase
          Issue Type: Improvement
    Affects Versions: 2.0.0
            Reporter: Chia-Ping Tsai
            Priority: Minor
             Fix For: 2.0.0


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.
