Kafka Connect ExtractNestedField SMT Usage Reference for Confluent Cloud

The ExtractNestedField single message transform (SMT) promotes a nested field within the Kafka Connect record key or value to a top level field. This SMT simplifies data access for downstream systems by extracting a required value (for example, ID) from a structure and placing it directly at the root level.

Limitations

• Although the SMT has the output.field.name configuration for renaming, the extracted field name defaults to the name of the nested field and cannot be customized.

Important

Confluent only supports this SMT on Confluent Cloud. For complete details, see the official ExtractNestedField SMT documentation.
