title: Can the Avro format be used for KSQL when using Apache Kafka without Confluent Platform?
body: <p>I see in the docs that KSQL supports the Avro format through the Confluent Schema registry. But what if Apache Kafka is being used (not Confluent Platform)? </p>
  
  <p>Is there an option to use an Avro SpecificRecord schema without using the schema registry?</p>
