Hi Willem, I agree to integrate a transaction tracking service, I used Zipkin, but I don't know much about Skywalking.
I have some questions: 1. Skywalking agent just working on the Omega side? 2. Use @Trace in the same location as @SagaStart and @Compensable, Or Combined annotation? And use TraceContext.traceId() to generate globalTxId or localTxId ? 3. Will Omega users have conflicts if they already use Zipkin? 4. About provides a service to bridge the Trace information that Skywalking collects with ServiceComb Pack Transaction events information. Do you mean that Alpha sends service chain information directly to Skywalking via API?
