Kafka connector: support for JSON, Protobuf formats with Confluent Schema Registry

[alexwirehead]

Hi. Are there any plans to add support for JSON, Protobuf formats in Kafka connector together with Confluent Schema Registry?

At the moment, according to the documentation, there is only AVRO support.

We tried to configure with JSON format but got an error:

2024-10-09T15:09:10.409Z WARN SplitRunner-20241009\_150909\_00009\_wcea6.2.0.0-1-236 io.trino.metadata.MetadataManager Failed to get metadata for table: kafka_test.default.trino-test ││ io.trino.spi.TrinoException: Not supported schema: JSON

@alexwirehead not at the moment but contributions are welcome :)

@wendigo Thank you for your reply. I would love to contribute, but unfortunately I have no experience in Java :(

But for schema registry integration we do have issues with Confluent as schema registry binaries for protobuf are backed by Confluent Community License https://www.confluent.io/confluent-community-license-faq/ - @mosabua/ @martint what's our plan for integrating such libraries ?
