Checking a user-defined aggregate (UDA)
In cqlsh, the DESCRIBE AGGREGATE
command outputs the full details of a user-defined aggregate.
Use the output from the DESCRIBE command to recreate the UDA.
This command requires a keyspace. Ideally you have also created an aggregate, but it isn’t required.
Verify that a UDA exists:
DESCRIBE AGGREGATE cycling.average;The response is the CREATE FUNCTION command that was used to create the function if it exists.
Otherwise, the response indicates that the function doesn’t exist.
