Producing messages doesn't encode magic byte and schema id

[tzachshabtay]

Using [email protected], I have a topic called test, I'm using the RecordNameStrategy and have registered a subject test in the schema registry.

Producing my message:

class test { }

const producer = await kafkaAvro.getProducer()
const data = new test()
data.long_field = 10
producer.produce('test', -1, data, 'key');

Produces the message but without the encoded schema.
The problem seem to stem from the fact that kafka-avro seems opinionated about the subject name (and I didn't see it mentioned in the docs). It seems to expect all topics to either end with -value or -key:

kafka-avro/lib/schema-registry.js

Line 356 in ee5fcaa

const parts = schemaTopic.split('-');

If it doesn't match that, it falls back and puts it in the keys schemas and doesn't put it in the values schemas:

kafka-avro/lib/schema-registry.js

Line 432 in ee5fcaa

if (schemaObj.schemaType.toLowerCase() === 'value') {

And then when it tries to produce the message it won't find the schema as it's not in the values schemas dictionary and fail to encode it.

This is the standard of schema-registry
