9.2. Kafka Bridge


9.2.1. OpenAPI v2 (Swagger)

Support for OpenAPI v2 is now deprecated and will be removed in Streams for Apache Kafka 3.0. OpenAPI v3 is now supported. Plan to move to using OpenAPI v3.

During the transition to using OpenAPI v2, the /openapi endpoint returns the OpenAPI v2 specification using an additional /openapi/v2 endpoint. A new /openapi/v3 endpoint returns the OpenAPI v3 specification.

9.2.2. Kafka Bridge span attributes

The following Kafka Bridge span attributes are deprecated with replacements shown where applicable:

  • http.method replaced by http.request.method
  • http.url replaced by url.scheme, url.path, and url.query
  • messaging.destination replaced by messaging.destination.name
  • http.status_code replaced by http.response.status_code
  • messaging.destination.kind=topic without replacement

Kafka Bridge uses OpenTelemetry for distributed tracing. The changes are inline with changes to OpenTelemetry semantic conventions. The attributes will be removed in a future release of the Kafka Bridge
