Which pattern should be used to invoke multiple HTTP APIs in parallel and roll back failed requests in sequence?

Show Suggested Answer Hide Answer
Suggested Answer: C

To invoke multiple HTTP APIs in parallel and roll back failed requests in sequence, the developer should use a Scatter-Gather router as a central Saga orchestrator for all API requests with compensating actions for failing routes. A Scatter-Gather router executes multiple routes concurrently and aggregates the results. A Saga orchestrator coordinates a series of actions across different services and handles failures by executing compensating actions. Therefore, using a Scatter-Gather router as a Saga orchestrator allows invoking multiple HTTP APIs in parallel and rolling back any failed requests in sequence.

Hmm, B sounds good too. Parallel processing with error handling could work well, especially for simpler use cases.

I think option C is the way to go. Scatter-Gather with a Saga orchestrator sounds like the most robust and scalable solution to me.
