If Option D doesn't work, I guess we could always try Option E: Throw the whole thing out and go back to monoliths. Just kidding, but seriously, D is the way to go.

D is the clear winner here. Who wants to deal with manual database locks and rollbacks when you can auMyate the whole process? Sign me up for the Choreographer and Event Bus!

Database lock required seems like a hassle. D is definitely the more efficient choice.

I think using store procedure/function from RDBMS could also be a good option for data consistency.

Hmm, I was leaning towards C until I read the details on D. Encapsulating the failure handling in a Choreographer is a much cleaner solution than trying to coordinate it across the individual services.

I'm not sure about the other options, but D definitely sounds like the most comprehensive approach. Handling failures across multiple services can be tricky, so having a centralized way to manage that is key.

Option D seems like the way to go. Using a Choreographer and Event Bus to handle failed scenarios seems like a robust and flexible solution for maintaining data consistency in a microservices architecture.
