Summary

Dataphos Schema Registry manages schemas for serialized data in streaming infrastructure and checks messages while they are in flight. It keeps versioned schema history and provides a REST API for schema management. Users can register, update, retrieve, or delete schemas, and check validity and compatibility. Supported schema formats include JSON, Avro, Protocol Buffers, XML, and CSV. Compatibility modes include backward, forward, and full compatibility, each with transitive variants, plus none; backward is the default. Validators support GCP Pub/Sub, Azure Service Bus, Azure Event Hubs, Apache Kafka, Apache Pulsar, and NATS JetStream. Messages are routed to a valid topic or a dead-letter topic according to validation results. The registry and validators run as Kubernetes deployments, with Shell, Helm, and Pulumi deployment options. The Shell quickstart calls for Kubernetes cluster nodes with at least 8 GB of available RAM. Dataphos is identified as a Syntio product. The registry is open source and available as an API or for self-hosting.
