Guangbin Zhu commented on FLINK-12256:
--------------------------------------
I skimed over the KafkaReadableCatalog design document.
I think when registering a kafka catalog , two parts of param are required:
* kafka connection params (zookeeper.connect, bootstrap.servers,
security.protocol etc) for connecting kafka cluster
* CSR related (CSR address, subject etc) for describing schema and converting
to Flink Table Data Type
I have a question:
How the consumer group.id/startup-mode stored in the catalog, is it static? I
think group.id/startup-mode are per application behavior params, each
application has it's own group.id/startup-mode . How the catalog describe a
table with group.id ? or the catalog does not store group.id/startup-mode ,
using as dynamic table options

> 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.

> Select * form kafka.topic_name
> {code}
> without the need for manual definition of the table schema.
