Support to be able to produce avro schema messages

[IlyaBSR]

Currently there is support to read from kafka topics using avro schema, but there is no capability to publish messages in AVRO schema.

docker run -t edenhill/kafkacat:20190711 -t topic-avro -b localhost:9093 -s avro -r https://${KAFKA_USERNAME}:${KAFKA_PASSWORD}@schema-registry.test.com -P % ERROR: -s serdes only available in the consumer

It would be great to also support TLS client auth for the schema registry, it seems that is not currently supported even for consuming (schema.registry.ssl.* configs seem to not be supported). I don't know if this warrants a separate ticket.

This is handled by libserdes, can you please file an issue here: https://github.com/confluentinc/libserdes/issues/new

Any status on the ability to produce Avro schema messages with schema registry?

For our use case, it would be useful to be able to say something like:

kcat -b broker -P -s avro -r https://schema-registry.local -Xserializer.framing=cp1 -Xkey.schema.subject=my-topic-key -Xvalue.schema.subject=my-topic-value -k '{"id":101}' '{myfield1: true, myfield2: "hello"}'

and

kcat -b broker -P -s avro -r https://schema-registry.local -Xserializer.framing=cp1 -Xkey.schema.id=23 -Xvalue.schema.id=94 -k '{"id":101}' '{myfield1: true, myfield2: "hello"}'

It seems pretty difficult to generate anything with avro from the cli using any tool.

@ahawtho does the command work?

It's been 4 years, and this issue is still open. @edenhill is it still not possible to produce message with a schema?
