We're currently in the process of adding Kafka support to EDFS (Event Driven Federated Subscriptions), a specification to add NATS, Kafka, and other pub sub or streaming services to a federated graph.
There's one thing missing and we could hook it up to your CDC solution. For each message, we need to set the __typename field. Does your solution have a way to accomplish this?
