Determining Stateless vs Stateful Microservices in MSCallGraph in MicroserviceTrace-v2021

How do we distinguish between stateless and stateful microservices in MicroserviceTrace-v2021? I noticed that the descriptions of MS_MCR_RT_Table and MS_Metrics_Table both explicitly say that all msnames in the tables represent stateless services. However, it seems like these two tables are not available to be downloaded as they are not in the four tables listed here.
Additionally, the description of MSCallGraph does not mention anything about only including stateless microservices. I have two questions:
1. Are the microservices (um and dm) in MSCallGraph all stateless or are they a combination of stateless and stateful services?
2. If they are a combination of both, is there some way to distinguish between stateless and stateful microservices in the MSCallGraph table?

Review the MicroserviceTrace-v2021 documentation for MSCallGraph, MS_MCR_RT_Table, MS_Metrics_Table, and the four listed downloadable tables. Determine whether um and dm are stateless or stateful and whether the MSCallGraph table exposes a distinguishing field; done means the documentation clearly answers both questions.
