Tyler Hobbs commented on CASSANDRA-6559:
----------------------------------------
I apologize for the slow feedback. There are a couple of issues with this
patch. First, we should be checking {{self.tty}} and only warning when that is
true so that we avoid prompting during a {{-f}} invocation. Second, I would
prefer to use cqlsh's parser for detecting the presence of ALLOW FILTERING
instead of using {{rindex()}} on the query string directly.
> cqlsh should warn about ALLOW FILTERING

> ALLOW FILTERING can be a convenience for preliminary exploration of your
> data, and can be useful for batch jobs, but it is such an anti-pattern for
> regular production queries, that cqlsh should provie an explicit warn
> ingwhenever such a query is performed.
