Add Support to Trigger and Output Bindings for Schema Registry
Since the function extension already supports Avro and Protobuf (de)serialization, it would be helpful to expose the following as optional configs for the KafkaTrigger
and Kafka
attributes.
-
schema.registry.basic.auth.credentials.source
-
schema.registry.basic.auth.user.info
-
schema.registry.url
Right now, to use Schema Registry (on Confluent Cloud, for example), the workaround is to declare KafkaEventData<string, byte[]>
and deserialize when you iterate over the record payload. The same is true for the output binding. You need to serialize and place the byte[]
in the IAsyncCollector<KafkaEventData<string, byte[]>>
instance.
While the manual (de)serialization isn't particularly difficult to use, IMHO, it would be a great addition for users of the extension function that aren't experienced working with Kafka. Plus, the function extension abstracts a lot of the "ceremony" of working with Kafka, and this would reduce it even further.
