Confluent Cloud Schema Registry Preview

Confluent Cloud Schema Registry is available as a preview feature. A preview feature is a component of Confluent Platform that is being introduced to gain early feedback from developers. These features can be used for evaluation and non-production testing purposes or to provide feedback to Confluent. Comments, questions, and suggestions related to preview features are encouraged and can be submitted to preview@confluent.io.

Supported Features

  • A single Schema Registry is available per environment (e.g. Prod, Dev).
  • Access Control to Schema Registry is based on API key and secret.
  • Each environment must have at least one Apache Kafka® cluster to enable Schema Registry.
  • Your VPC must be able to communicate with the Confluent Cloud Schema Registry public internet endpoint. For more information, see Using Confluent Cloud Schema Registry in a VPC Peered Environment.
  • Only available in the US region.
