When user defined as mapping from any DBMS to Kafka target using Schema Registry/Avro, a topic is created in Kafka and a subject with a initial version of schema is created in Schema Registry.

The Avro definition will contain a JSON like string that reflects the fields definitions of mapped source fields.

To trigger a refresh and generate a source table DDL change
  1. Refresh source table in Director's catalog to retrieve the definition after DDL change.
  2. Generate a new schema version for the subject in Schema Registry based on the new source table fields definition.
  3. Refresh target topic definition in Director to reflect the new schema version.
  4. Refresh the fields mapping in Director to:
    • Remove suppressed fields
    • Add new fields added and default map them with "Copy method"

This feature can be access from the GUI menu by right-clicking a mapping.
