+
+ Output CQL commands that could be used to recreate the given index.

+ DESCRIBE CLUSTER
+
+ Output information about the connected Cassandra cluster, such as the

+
+ 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.
+
