Cassandra: How to generate uuid?

'uuid()' function generates an uuid of type 4.

Example

CQL code snippet

CREATE KEYSPACE cassandratutorial WITH REPLICATION = 
{ 
  'class' : 'SimpleStrategy', 
  'replication_factor' : 1 
};

CREATE TABLE IF NOT EXISTS cassandratutorial.employee (
  id uuid PRIMARY KEY, 
  first_name VARCHAR
);

INSERT INTO cassandratutorial.employee(id, first_name) VALUES (uuid(), 'Krishna');

Cqlsh console output

cqlsh> CREATE KEYSPACE cassandratutorial WITH REPLICATION = 
   ... { 
   ...   'class' : 'SimpleStrategy', 
   ...   'replication_factor' : 1 
   ... };
cqlsh> 
cqlsh> CREATE TABLE IF NOT EXISTS cassandratutorial.employee (
   ...   id uuid PRIMARY KEY, 
   ...   first_name VARCHAR
   ... );
cqlsh> 
cqlsh> INSERT INTO cassandratutorial.employee(id, first_name) VALUES (uuid(), 'Krishna');
cqlsh> 
cqlsh> SELECT * FROM cassandratutorial.employee;

 id                                   | first_name
