AVRO schema refs with Hamba avro about avro HOT 8 CLOSED

What have you tried that is not working?

from avro.

How to publish the data with using union schema? Any examples around that? I want to get some reference how can we do that at the publisher side, and how would we know which schema should be validated against the payload?
Any examples for the same would be appreciated.

@nrwiersma any help on this?

from avro.

Sure, I suggest you read the README on type conversions, specifically on unions: https://github.com/hamba/avro#types-conversions
and check out the examples on using the library here: https://pkg.go.dev/github.com/hamba/avro/v2#example-package-Usage.

@nrwiersma I have the code implemented, the thing is if I have 7 sub-schemas referenced under a union schema, then i'm making 7 avro conns to each of the sub-schemas and using hamba-avro package for parsing and binding the messages. But the thing is I should be able to do this with a single avro conn with union-schema(that contains the reference to all thee sub-schemas), any specific examples around that?

from avro.

No, that is a really specific thing to do, and not the "basic" case, which is what is covered in the docs. I would suspect it is no different from encoding anything other schema data.

@nrwiersma How will we get to know which schema to use from the union-schema refs for marshalling the payload?

from avro.

It will be based on the data/payload you are encoding. If you use a map, the first and only key is used to select the type/name of the schema, if it is an interface, it will resolve the schema from the registrar. This is all explained in the README.
