> Runtime-configurable YAML option to prohibit USE statements

> Key: CASSANDRA-17318
> URL: https://issues.apache.org/jira/browse/CASSANDRA-17318
> Project: Cassandra
> Issue Type: Improvement
> Components: CQL/Syntax
> Reporter: Caleb Rackliffe
> Assignee: Caleb Rackliffe
> Priority: Normal
> Fix For: 4.x
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> The ambiguity around prepared statements without fully qualified table names
> has led to a number of sub-optimal outcomes for our users. With
> CASSANDRA-15252 and CASSANDRA-17248 resolved, there aren't any lingering
> _known_ issues, but operators may still want to cordon {{USE}} statements off
> completely. This is especially important if we plan to deprecate and remove
> {{USE}} at some point in the future.
> A couple details...
> 1.) The new option will be opt-in.
> 2.) It will be possible to change at runtime.
> 3.) There will be a new metric for {{USE}} that tells us whether it's been
> used at all. (This should make it easier to disable {{USE}} for an existing
> cluster where we don't know a-priori that it isn't in play.)
