Alright, everyone, no need to partition your brains trying to figure this one out. Just focus and choose wisely. No pressure, though. *winks*

Wait, what? All of them? That seems a bit excessive. Maybe the exam writer is just trying to see if we're paying attention. *chuckles* I'll go with the ones that make the most logical sense.

Ah, I see what they're getting at. A is also correct, the existing records will get rebalanced across the new partitions. Guess I better brush up on my partition management skills!

Hold on, I'm pretty sure C is also correct. Increasing the number of partitions means new records might get written to a different partition, not just the old ones. Gotta be careful with these tricky questions!

Hmm, I think B and D are the correct answers. The old records will stay in their partitions, and the new records with the same key will get written to the same partition as the old ones. Simple enough, right?

Yes, and D is also correct because old records will stay in their partitions.

I'm not sure about C. I think new records may get written to a different partition when we increase the number of partitions. Can someone clarify this?

I agree with Chuck. It makes sense that old records will stay in their partitions and new records with the same key will go to the same partition.

I think A and B are correct. When we increase partitions, existing records will be rebalanced and new records with the same key will go to the same partition.
