Hi, As ServiceComb Pack use the GlobalTransactionId to trace the distributed transactions, it's make sense that let the ServiceComb Pack and Skywalking share the same Id for tracing. In this way, we can bring the APM feature into Distribution Transaction managemet world.
Current ServiceComb has Interface IdGenerator[1], which is used for the generate the GlobalTransactionId in OmegaContext[2]. I think if we can reuse the transaction implementation with the Skywalking agent to generate the GlobalTransactionId. In this way we can search the trace information and transactions with same correlation ID. The missing part is LocalTransactionId, we need to figure a way to bring the LocalTransactionId with the trace information. BTW, ServiceComb Pack is using ES to store the Transaction related event[3]. I think we can provide a service to bridge the Trace information that Skywalking collects with ServiceComb Pack Transaction events information. Any thoughts?
