Wait, can we really handle tens of thousands of messages like that?

Not sure about that, seems like it could introduce delays.

I think creating the pipeline statically might not be flexible enough for handling the dynamic nature of incoming messages. It feels like we need a more adaptive approach.

I recall a similar question where we had to think about how to manage high throughput. I wonder if creating a new object in the startBundle method would help with managing state.

I'm not entirely sure, but I think calling out to the service via HTTP might lead to issues if we have too many concurrent requests. It feels risky.

I remember we discussed the importance of batching in our last practice session. It seems like option D could help with backpressure by reducing the number of calls made to the service.

This question seems straightforward, but I want to make sure I understand the key differences between FRAs and STIR futures before selecting an answer.

Hmm, I'm a little unsure about this one. The question is asking about the default entry point, but the options don't seem to match what I've learned. I'll have to think this through carefully.

I'm pretty sure the default port for a Runtime Resource is 8181, but I know it's configurable. I'll double-check the documentation just to be sure.

This looks like a straightforward accounts receivable calculation, but I'll need to be careful to account for all the changes in the credit policy.
