I feel like there was something about testing being easier with batch deployments, but I'm not completely confident in that.

I think we had a practice question about the advantages of batch vs. real-time, but I can't recall the specifics.

I'm not entirely sure, but I feel like querying stored predictions could be faster than computing them on the fly.

I remember discussing batch serving in class, and I think it can be more efficient when you have data ready in advance.

I've got this! Batch serving can be faster since the predictions are pre-computed. That could be a big advantage in this scenario.

Wait, I'm a bit confused. Isn't real-time serving supposed to be more up-to-date? I'll need to re-read the question carefully.

Okay, let's see. If the feature values are available a week in advance, then batch serving could be faster than real-time. I'll make sure to consider that.
