> In CASSANDRA-21179 we have introduced training_min_frequency to prevent from exhaustive training. It might be improved in such a way that there would be a guardrail which would fail table creation / alternation when this parameter is not set. By doing so, an operator would declare that there has to be minimum training frequency set for all to-be-created tables in the future, if there is such a requirement.
