I agree, using orderDate as the partition key is a bad idea. It's like trying to fit a million orders into a single shoebox - it just ain't gonna work!

Yikes, I hope they don't choose orderDate as the partition key. That would be a recipe for disaster, like trying to fit a square peg in a round hole!

Not to mention, there will always be a hot partition as new orders come in. That could lead to uneven distribution of the workload.

But wouldn't using orderDate as the partition key make queries more efficient for viewing past order history?

Exactly! And with one million orders daily, we'll likely exceed the maximum storage per partition too. This could cause performance problems.

Using orderDate as the partition key doesn't sound like a good idea. We'll have too many partition key values and that could lead to issues with the maximum number of partitions.
