Check a user-defined function (UDF)
In cqlsh, the DESCRIBE FUNCTION
command outputs the full details of a user-defined function.
Use the output from the DESCRIBE command to recreate the UDF.
This command requires a keyspace. Ideally you have also created a function, but it isn’t required.
Verify that a UDF exists:
DESCRIBE FUNCTION cycling.flog;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.
