Adding schemas to the Schema Registry

Learn how to add new schemas to Schema Registry so that you ensure data consistency across your data pipeline.

Schema Registry provides a shared repository for your schemas to ensure that your data is accessible across the data pipeline.

  • WeatherCurrent
  • WeatherForecast
  1. Log in to the CDP web interface.
  2. Go to Management Console > Data Hub Clusters and select the CMM cluster that you created earlier.
  3. Click Schema Registry under the Services section.
    The All Schemas page is displayed.
  4. Click .
    The Add New Schema page is displayed.
  5. Add the schema metadata as follows:
    Field nameDescription and values
    NAME Used as a key to look up schemas. Specify WeatherCurrent and WeatherForecast if you are trying the Business Intelligence at Scale pattern.
