Jon Hermes commented on CASSANDRA-2221:
---------------------------------------
CASSANDRA-1906 completes the YAML removal (all that's left is with on-boot yaml
load of per-node settings, which is fine as is).
Tying this right next to the 'show keyspaces;' logic (maybe 'export
keyspaces;') is going to be the easiest, as it already iterates through your
settings.
Instead of showing shorthand (" default_validation_class: BytesType"), show
longhand ("with default_validation_class=BytesType ") and cascade them into a
"create column family ... " output.
> 'show create' commands on the CLI to export schema

> Issue Type: Improvement
> Components: Tools

> Fix For: 0.7.4

>
> 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.
