Wait, can you really do ACID with Cosmos DB? Sounds tricky!

You need an unsharded collection for ACID transactions.

I recall that unsharded collections can simplify things, but I wonder if they support ACID operations effectively for multiple documents.

I’m a bit confused about the APIs. I thought the MongoDB API could handle multiple document updates, but I’m not entirely sure.

I think we practiced a similar question where we had to decide between sharded and unsharded collections. I feel like sharding on username might help with performance.

I remember we discussed the importance of ACID transactions in Cosmos DB, but I'm not sure which API to choose for this scenario.

Alright, I've got a plan. I think creating a sharded collection on the username field is the way to go. That should allow me to update multiple documents for a single user in a single ACID operation.

Okay, let's see here. The key things I'm looking for are the ability to update multiple documents for a single username in a single operation. I think the sharding option might be the way to go, but I'll need to double-check the details.

Okay, resetting the ports for the specific FC IDs seems like the most direct approach. I'll make sure to double-check the IDs mentioned in the question.

I think if the deterioration rates are low, going for on-stream inspection could be the best option, but I'm not entirely sure if that's what we discussed in class.
