Subject [jira] Commented: (CASSANDRA-1072) Increment counters
Date Wed, 15 Dec 2010 19:20:16 GMT


Kelvin Kakugawa commented on CASSANDRA-1072:

I was looking through the code and thought about it more.

We can't remove value ser/des, because we need to serialize it for the commit log (and hinted
hand-off).  So, value needs to be serialized, at some point.  So, the disk format won't change.

However, we can optimize the code to not recalculate the total on every update w/o read. 
Looking into this.

two features but without the plain version vector code the changeset becomes smaller and more
