Description

For the project I am working the data is formatted as describe for the AVRO project (see https://avro.apache.org/docs/1.10.2/gettingstartedpython.html ). After doing some searching on google, fastapi doc and github I could not find anything. So reaching out to you.

Hi @mbrookhuis, please provide an example on your attempt to use avro schema. I know you could use it with pydantic with pydantic-avro, but I am not sure how that would behave with FastAPI. You could try and share results/issues.

Perhaps the payload being Avro? I don't see why it couldn't be done with a midlewar

Yeah this question is very broad. You basically have two options:

• AVRO as string; since Avro is basically JSON in syntax, you could just provide it as a body like {"avro_string":"{u'favorite_color': None, u'favorite_number': 256, u'name': u'Alyssa'}"} and parse it from there.
• AVRO as binary file: if you receive it as a binary file, you can use the normal File or UploadFile stuff in FastAPI and parse it with any of the standard libraries dealing with Avro.

I'm assuming the binary and associated mime type is the way to go
