DataStax Academy migrated to a new learning management system (LMS) in July 2020. We are also moving to a new Cassandra Certification process so there are changes to exam bookings, voucher system and issuing of certificates.
Check out the Academy FAQ pages for answers to your questions:
the USING TTL clause on UPDATE/INSERT query should be placed at the beginning of the query
as in:
UPDATE users USING TTL 10 SET favs['color'] = 'green' WHERE id = 'jsmith'
The Node.js mapper places the USING clause at the end: https://github.com/datastax/nodejs-driver/blob/master/lib/mapping/query-generator.js#L129
Thanks Emile!
I've created a ticket to track it: https://datastax-oss.atlassian.net/browse/NODEJS-538
