>                 Key: CASSANDRA-893
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-893
>             Project: Cassandra
>          Issue Type: Bug
>            Reporter: Chris Goffinet
>            Priority: Minor
>
> I noticed this in HHManager:
> TODO handle rows that have incrementally grown too large for a single message.)
> In CASSANDRA-883 I had noticed a lot of CPU burning cycles. I was unable to figure out
until tonight why this was. We had a very very large row (9.2M+ columns). If this row ever
got hinted, it was trying to load entire row into memory. 
> It might be a good idea to actually add paging support (send target multiple row mutations)
so that we don't have read the _entire_ row into memory.
