Need help with output.schema.key

I want to send to store message to a specific partition. But I can’t understand how they configured output.shcema.key in this example posted on Git of a MongoDB specialist. Can anyone help me understand how he mentioned output.schema.key as animal_type? Thanks a lot in advance

Can you paste the link to which example you are referring?

Its your article sir :grin:

output.schema.key is the avro representation (not JSON schema) of the message event.
