----------------------------------
Hi Jonathan,
I was actually talking about 2. even with the "query cache" will it make sense
to add the upper bound? so that we dont waste resources doing copies?
> Make Row cache reject wide rows which are more than x columns
> -------------------------------------------------------------

> Key: CASSANDRA-3383
> URL: https://issues.apache.org/jira/browse/CASSANDRA-3383
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Affects Versions: 1.1
> Environment: Linux with Sun JDK
> Reporter: Vijay
> Assignee: Vijay
> Priority: Minor
>
> The problem with the row cache is it has to cache the whole row into the
> memory, this works great for small rows but not for the wide rows. Even
> off-heap cache has to read everything into the heap eventually causing GC
> overhead (If your query is to get few columns).
> It will be nice to reject the rows which are bigger than x columns (This can
> be a KS setting).... this will help cases where we have mixed load of small
> and wide column datasets in the same cf.
