You have a container m an Azure Cosmos DB for NoSQL account. The container stores data about families. Data about parents, children, and pets are stored as separate documents.

Each document contains the address of each family. Members of the same family share the same partition key named family Id

You need to update the address for each member of the same family that share the same address. The solution must meet the following requirements:

* Be atomic consistent isolated, and durable (ACID).

* Provide the lowest latency.

I love how they sneak in that 'lowest latency' requirement. Very sneaky, Azure Cosmos DB. Option A gets my vote.

Option C seems like overkill. Strong consistency is great, but do we really need it for a simple address update? A is the clear winner here.

That's a good point, Elizabeth. However, using a transactional batch operation would provide the lowest latency as well.

But wouldn't updating the document of each family member separately with strong consistency also meet the requirements?

I agree with Cordelia. Using a transactional batch operation ensures atomicity and consistency.

I was leaning towards option B, but the requirement for low latency makes me think A might be the better choice. Batched operations should be faster.

C) Setting the consistency level to strong might also help ensure data integrity.

Hmm, I think option A is the way to go. Updating all family members in a single transaction seems like the best way to ensure ACID compliance.
