WarpStream BYOC Schema Registry

What WarpStream BYOC Schema Registry is

WarpStream BYOC Schema Registry stores and serves schemas used to serialize, deserialize, and validate Kafka records. It exposes a REST server compatible with Confluent’s Schema Registry API and supports Avro and protobuf. The stateless registry stores schemas in the customer’s object store, with registry functionality embedded in WarpStream Agents; WarpStream says schemas stay within the customer’s cloud account and storage buckets. Agents can check records against schemas, rejecting invalid records or emitting metrics. Schema Linking can move schemas from a Confluent-compatible registry while retaining IDs and compatibility rules. Schema Validation also works with Kafka-compatible registries such as Confluent Schema Registry and AWS Glue Schema Registry. Authentication options include Basic Authentication, TLS, and mutual TLS. Customers can create a Schema Registry Virtual Cluster in the console or through the API and deploy its agent using the Kafka Agents binary. Agents emit logs and metrics for monitoring. Limits are 100,000 schema versions per registry and 1 MB per schema; customers can request increases.
