Robin Moffatt looks into additions to KSQL with Confluent Platform 5.2:

PRINT is one of those features you may not quite grok until you start using it…and then you’ll wonder how you lived without it. It provides a simple way of displaying the contents of a Kafka topic and figures out itself which deserialiser to use. Avro? No problem! JSON? Bring it on!

These are some good additions.

Databricks Runtime 5.3 and 5.3 ML and above support […]

This will happen in every machine with the relevant […]
