Timo Walther commented on FLINK-8538:
-------------------------------------
[~xccui] thanks for working on this issue. This issue depends on general
changes we want to do regarding formats. I will open further issues as
blockers. The idea is to have some means to perform {{format}} discovery such
as Avro, JSON, Protobuff, XML, etc. similar to how the file system discovery
works now. The {{KafkaTableSource}} factory would be located in {{flink-kafka}}
and instantiates the needed format. {{flink-kafka}} will only have an optional
dependency on {{flink-table}} as it is also done at the moment.
> Add a Kafka table source factory with JSON format support

> Issue Type: Sub-task
> Components: Table API & SQL
> Reporter: Timo Walther
> Assignee: Xingcan Cui
> Priority: Major

> Similar to CSVTableSourceFactory a Kafka table source factory for JSON should
> be added. This issue includes improving the existing JSON descriptor with
> validation that can be used for other connectors as well. It is up for
> discussion if we want to split the KafkaJsonTableSource into connector and
> format such that we can reuse the format for other table sources as well.
