OTEL Kafka Exporter

Is your feature request related to a problem?

In some cases it is good to export spans, logs, and metrics direct to Kafka, rather than elsewhere. For example, all your applications could publish to a Kafka cluster/s, with an OpenTelemetry Collector configured to export elsewhere. If you then wanted to change where you wanted to export your telemetry data you would only need to update the configuration for a single deployment

Describe the solution you'd like

Exporters that publish to Kafka. Defaults should match those of the Kafka Receiver from the opentelemetry-collector. For example the default topic for traces would be otlp_spans

Tip

_{React with 👍 to help prioritize this issue. Please use comments to provide useful context, avoiding +1 or me too, to help us triage it. Learn more here.}

Start by reading the linked OpenTelemetry Collector Kafka Receiver README and inspect the opentelemetry-python repository for existing exporter entry points. Define the scope for spans, logs, and metrics, including the requested Kafka defaults such as the otlp_spans topic. Done means the requested Kafka exporters are implemented and covered by the repository's tests.
