Dave Brosius commented on CASSANDRA-4052:
-----------------------------------------
Is this schema cached to allow for the assumption of cf attributes?
ie, assume cf validator as utf8;
?
> Add way to force the cassandra-cli to refresh it's schema

> Key: CASSANDRA-4052
> URL: https://issues.apache.org/jira/browse/CASSANDRA-4052
> Project: Cassandra
> Issue Type: Improvement
> Components: Tools
> Affects Versions: 1.0.8
> Reporter: Tupshin Harper
> Priority: Minor
>
> By design, the cassandra-cli caches the schema and doesn't refresh it when
> various commands like "describe keyspaces" are run. This is reasonable, and
> it is easy enough to restart the cli if necessary. However, this does lead
> to confusion since a new user can reasonably assume that describe keyspaces
> will always show an accurate current represention of the ring. We should find
> a way to reduce the surprise (and lack of easy discoverability) of this
> behaviour.
> I propose any one of the following(#1 is probably the easiest and most
> likely):
> 1) Add a command (that would be documented in the cli's help) to explicitly
> refresh the schema ("schema refresh", "refresh schema", or anything similar).
> 2) Always force a refresh of the schema when performing at least the
> "describe keyspaces" command.
> 3) Add a flag to cassandra-cli to explicitly enable schema caching. If that
> flag is not passed, then schema caching will be disabled for that session.
> This suggestion assumes that for simple deployments (few CFs, etc), schema
> caching isn't very important to the performance of the cli.
