I'm somewhat of an AWS noob, and have just started working with Lambda task-based step functions and state machines. I created a multi-step state machine that passes a a request object from step to step and acts on it. What I don't understand is how I would execute the state machine for a large number requests. Would I simply call "start execution" for every request, even if there are 1000s, or is there a more efficient way to handle it? Any thoughts on approach would be appreciated.
You can run multiple state machines at the same time, but keep in mind the service limits for both Step Functions and your Lambda tasks.
Based on the limits for open executions (1,000,000 at the time of writing this), the service is built to handle thousands at a time.
