-------------------------------------
Labels: client-impacting cql3 (was: cql3)
> Server-side DESCRIBE
> --------------------
>
> Key: CASSANDRA-8005
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8005
> Project: Cassandra
> Issue Type: New Feature
> Components: API
> Reporter: Tyler Hobbs
> Priority: Minor
> Labels: client-impacting, cql3
> Fix For: 3.0
>
>
> 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.
