Setting a Schema Registry ID range

Learn how to set an ID range for schemas in Schema Registry using Cloudera Manager.

An ID range that is unique to a Schema Registry instance can be set in Cloudera Manager on the Schema Registry service’s configuration page. Configuring an ID range does not alter already existing schemas.

  • Ensure that the cluster, its hosts, and all its services are healthy.
  • Ensure that Schema Registry is commissioned and running.
  • Ensure that you have access to all credentials that are required to access and use Schema Registry.
  • Plan ahead and designate ID ranges for each Schema Registry instance. Ensure that the planned ranges do not overlap.
  • Ensure that the ID range you plan to configure has enough IDs. Base the size of your range on the approximate number of schemas you expect to have.
  1. In Cloudera Manager, select the Schema Registry service.
  2. Go to Configuration.
  3. Find and configure the following properties:
    • ID Offset Range Minimum
    • ID Offset Range Maximum

    Configure the properties according to your planned ID ranges. For example, if you want to have an ID range of 1-100, set ID Offset Range Minimum to 1 and ID Offset Range Maximum to 100.

  4. Click Save Changes.
  5. Restart the Schema Registry.
When new schemas are added, either with the UI or the API, the schema IDs are allocated from the configured range.
