Azure Schema Registry

What Azure Schema Registry is

Azure Schema Registry is a cloud service for organizing schemas used to validate events. It supports Avro, JSON Schema, and Protobuf, with Backward, Forward, and None compatibility modes. The service is available through the web and has paid plans, with no free plan. Standard provides a 25 MB registry, 25 schema versions, and up to 7 days of event retention. Premium provides a 100 MB registry, 100 schema groups, 1,000 versions, and up to 90 days of retention. Dedicated provides a 1,024 MB registry, 1,000 schema groups, 10,000 versions, and up to 90 days of retention. Standard capacity is billed per throughput unit per hour, while Premium capacity is billed per processing unit per hour; prices depend on region and currency. Dedicated usage is charged in one-hour increments, with a minimum charge of four hours. These plan limits set the available registry size, schema organization capacity, and retention period for teams managing event schemas.
