>  KafkaReadableCatalog is a special implementation of ReadableCatalog interface (which introduced in [FLIP-30|https://cwiki.apache.org/confluence/display/FLINK/FLIP-30%3A+Unified+Catalog+APIs] )  to retrieve meta information such topic name/schema of the topic from Apache Kafka and Confluent Schema Registry. 
> New ReadableCatalog allows a user to run SQL queries like:
> {code:java}
> Select * form kafka.topic_name  
> {code}
> without the need for manual definition of the table schema.
