-
- (DESC may be used as a shorthand.)
-
- Outputs information about the connected Cassandra cluster, or about

-
- DESCRIBE KEYSPACES
-
- Output the names of all keyspaces.
-
- DESCRIBE KEYSPACE [<keyspacename>]
-
- Output CQL commands that could be used to recreate the given
- keyspace, and the tables in it. In some cases, as the CQL interface
- matures, there will be some metadata about a keyspace that is not
- representable with CQL. That metadata will not be shown.
-
- The '<keyspacename>' argument may be omitted when using a non-system
- keyspace; in that case, the current keyspace will be described.
-
- DESCRIBE TABLES
-
- Output the names of all tables in the current keyspace, or in all
- keyspaces if there is no current keyspace.
-
- DESCRIBE TABLE <tablename>
-
- Output CQL commands that could be used to recreate the given table.
- In some cases, as above, there may be table metadata which is not
- representable and which will not be shown.
-
- DESCRIBE INDEX <indexname>
-
- Output CQL commands that could be used to recreate the given index.
- In some cases, there may be index metadata which is not representable
- and which will not be shown.
-
- DESCRIBE CLUSTER
-
- Output information about the connected Cassandra cluster, such as the
- cluster name, and the partitioner and snitch in use. When you are
- connected to a non-system keyspace, also shows endpoint-range
- ownership information for the Cassandra ring.
-
- DESCRIBE [FULL] SCHEMA
-
- Output CQL commands that could be used to recreate the entire (non-system) schema.
- Works as though "DESCRIBE KEYSPACE k" was invoked for each non-system keyspace
- k. Use DESCRIBE FULL SCHEMA to include the system keyspaces.
-
- DESCRIBE FUNCTIONS <keyspace>
-
- Output the names of all user defined functions in the given keyspace.
-
- DESCRIBE FUNCTION [<keyspace>.]<function>
-
- Describe the given user defined function.
-
- DESCRIBE AGGREGATES <keyspace>
-
- Output the names of all user defined aggregates in the given keyspace.
-
- DESCRIBE AGGREGATE [<keyspace>.]<aggregate>
-
- Describe the given user defined aggregate.
-
- DESCRIBE <objname>
-
- Output CQL commands that could be used to recreate the entire object schema,
- where object can be either a keyspace or a table or an index (in this order).
