Description

It would be nice to have 'show create' type of commands on the command-line so that it would generate the DDL for the schema.

A scenario that would make this useful is where a team works out a data model over time with a dev cluster. They want to use parts of that schema for new clusters that they create, like a staging/prod cluster. It would be very handy in this scenario to have some sort of export mechanism.

Another use case is for testing purposes - you want to replicate a problem.

We currently have schematool for import/export but that is deprecated and it exports into yaml.

This new feature would just be able to 'show' - or export if they want the entire keyspace - into a script or commands that could be used in a cli script. It would need to be able to regenerate everything about the keyspace including indexes and metadata.
