Nick Bailey commented on CASSANDRA-8005:
----------------------------------------

bq. Support writing out schemas where it makes sense.

bq. I don't see how this is better done by this feature than by the existing 
KeyspaceMetadata.exportAsString method the java driver already provided.

So I think the point here is to have the cassandra server itself do this. We 
already have CASSANDRA-7190 for example. We could dump relevant info from the 
schema tables so that a client could consume that but I like the idea of a 
CREATE string a lot more.

> The various {{DESCRIBE}} commands are currently implemented by cqlsh, and 
> nearly identical implementations exist in many drivers.  There are several 
> motivations for making {{DESCRIBE}} part of the CQL language:
> * Eliminate the (fairly complex) duplicate implementations across drivers and 
> cqlsh
> * Get closer to allowing drivers to not have to fetch the schema tables. 
> (Minor changes to prepared statements are also needed.)
> * Have instantaneous support for new schema features in cqlsh.  (You 
> currently have to update the bundled python driver.)
> * Support writing out schemas where it makes sense.  One good example of this 
> is backups.  You need to restore the schema before restoring data in the case 
> of total loss, so it makes sense to write out the schema alongside snapshots.
