[jira] Commented: (CASSANDRA-645) replace RowMutation w/ serialized thrift structs

["Gary Dusbabek (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-645?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12793416#action_12793416 ] 

Gary Dusbabek commented on CASSANDRA-645:
-----------------------------------------

I still don't get where the extra copy is happening.  Are you referring to serialization/deserialization operations?  Do you mean that the creation of RowMutation should be pushed down to be as near to the actual write as possible?

> using the client's representation internally will save basically a copy operation on the critical write path
