> While investigating the issue CASSANDRA-9678 I noticed a number of
> inconsistencies in the way 'describe' operates, so I'm opening a new issue to
> address these. This issue will also address CASSANDRA-9678.
> I'd be happy to work on this.
> There are a number of inconsistencies in the way 'describe' operates within
> cqlsh, and also in the 'help describe' description within cqlsh compared to
> the CQL documentation (at
> http://docs.datastax.com/en/cql/3.3/cql/cql_reference/describe_r1.html)
> For example, 'desc functions' will list all functions for all keyspaces
> regardless of whether there is a current keyspace or not, whereas 'desc
> tables' or 'desc types' will list only the tables or types for the current
> keyspace.
> Some commands exist in cqlsh that are not in the CQL documentation, nor in
> the 'help describe' description. For example, 'desc functions' is a valid
> CQLSH command but does not appear in either the CQL docs or 'help describe'.
> I suggest we align the way the 'describe' command works so that it works
> consistently regardless of whether it is describing a table, type, function
> or any other database object, and also update the CQL and 'help describe'
> docs to match. Since 'describe tables' and it's variants has been around the
> longest we should probably align other 'describe' commands to 'describe
> tables'.
> My preliminary analysis has shown at least the following inconsistencies:
> - 'desc functions' (with current keyspace), differs from 'desc tables' and
> 'desc types'.
> - a number of commands are missing from the CQL docs or 'help describe, such
> as: desc table <keyspace>.<tablename>, desc functions (no current keyspace),
> desc function <function name>, desc type <keyspace>.<type name>, etc.
