> Cassandra newcomers often don't understand that they're expected to use PreparedStatements
for almost all of their repetitive queries executed in production.
> It doesn't look like Cassandra currently expose any PreparedStatements related metrics.It
would be interesting, and I believe fairly simple, to add several of them to make it possible,
in development / management / monitoring tools, to show warnings or alerts related to this
bad practice.
> Thus I would suggest to add the following metrics:
> * Executed prepared statements count
> * Executed unprepared statements count
> * Amount of PreparedStatements that have been registered on the node
