The current test TestCassandraConnectorTest has some issues:

• Unrelated types in a table
• The definition and data are managed in the different class
• Less coverage in a type

It would be nice to introduce type mapping tests.

I'm not sure how feasible this may be, but the old logparser program from Microsoft supported queries like

Select * from test.csv

And it would read from test.csv, without needing any config files.

Calling db.Drop when a bucket does not exist returns "bucket not found" and that error is directly from bolt's bolt.ErrBucketNotFound, I believe this error should be translated to storm.ErrNotFound.

Is your feature request related to a problem or challenge? Please describe what you are trying to do.
I am trying to programatically create Exprs that represent function calls, for example to_timetsamp(x, 4) or something

To do so today you have to do something like this (from simplify_expressions.rs) which is 🤮

        // to_timestamp("2020-09-08T12:00:00+00:00")
       

It's possible to pass more query bindings than there are bindvars in a query. This should be an error.

Per discussion in #2743 this class is mis-named.

Also, rename LinkStreamValue to just plain LinkStream.
