Also, what command can I used to see the "caching" setting?  "DESC TABLE <cf>" doesn't
list caching at all.  Thanks.

Hi Bryan,

Thank you very much for this information.  So in other words, the settings such as row_cache_size_in_mb in
YAML alone are not enough, and I must also specify the caching attribute on a per column family

It's a per column family setting that can be applied using the CLI or CQL.

With CQL3 it would be

ALTER TABLE <cf> WITH caching = 'rows_only';

to enable the row cache but no key cache for that CF.
