• The processor documentation is missing sub-documentation for otel_trace_raw and service_map_stateful. I hope the documentation can add some explanation.
• In https://opensearch.org/docs/latest/data-prepper/common-use-cases/trace-analytics/#processor, it is mentioned that there are processors named service_map_stateful and otel_traces_raw.

• Interestingly, https://opensearch.org/docs/latest/data-prepper/pipelines/configuration/processors/processors/ does not mention the existence of service_map_stateful and otel_traces_raw at all.

@linghengqian , The otel_trace_raw is the deprecated name for otel_traces. See https://github.com/opensearch-project/data-prepper/blob/db9a849b388780c151942931ea6c64350c00c185/data-prepper-plugins/otel-trace-raw-processor/src/main/java/org/opensearch/dataprepper/plugins/processor/oteltrace/OTelTraceRawProcessor.java#L39.

The same is true of service_map_stateful.

Would you be interested in updating the documentation with information on these?
