[jira] [Created] (HBASE-25187) Improve SizeCachedKV variants initialization

ramkrishna.s.vasudevan created HBASE-25187:
----------------------------------------------

             Summary: Improve SizeCachedKV variants initialization
                 Key: HBASE-25187
                 URL: https://issues.apache.org/jira/browse/HBASE-25187
             Project: HBase
          Issue Type: Improvement
            Reporter: ramkrishna.s.vasudevan
            Assignee: ramkrishna.s.vasudevan
             Fix For: 3.0.0-alpha-1, 2.3.3


Currently in SizeCachedKV we get the rowlength and Key length from the buffers. This can be optimized because we can pass the keylen and row len while actually creating the cell while reading the cell from the block.  Some times we see that the SizeCachedKV takes the max width in a flame graph - considering the fact we also do a sanity check on the created KV.
