Adding metadata won't solve the problem, B is the best choice.

C is misleading, we can reserve a partition for ABC.

Wait, can we really reserve a partition like that?

I think a custom partitioner is the way to go!

I think we practiced a similar question where we had to manage partitions based on keys. Creating a custom partitioner sounds familiar, so I lean towards B as well.

I'm not entirely sure, but I feel like option C is saying that we can't really reserve a partition for ABC. That seems a bit limiting, though.

I remember we talked about custom partitioners in class. I think option B might be the right choice since it allows us to control how messages are distributed.

I vaguely recall something about metadata and producers, but I don't think that would help us reserve a partition. So, I guess that rules out option A for me.

Hmm, this looks like a tricky one. I'll need to carefully examine the table structure and the SQL statements to determine how the view and table changes might impact the final code block.

Okay, I've got this. The key is to identify the common characteristics of poorly functioning teams and then find the one that doesn't fit.

Multi-Account Onboarding sounds familiar, but I don't see how that fits here. It seems like this problem is more about restricting access specifically.

I think the key here is the concept of control versus significant influence. OP is a subsidiary since LM owns 55%, but QR and ST are more complicated.
