Funny, I was just last week having an argument with one of our team leads. I'd told him to create a specific container without a partition key (which I wouldn't recommend except in certain circumstances), and he said he couldn't. I assumed he was just doing it wrong.

In a document store, what does it even mean to create a container without a partition key? The document store has to partition the data somehow, and doing so implicitly sounds dangerous to me since all you're doing is creating a hotspot on one of the partitions...

It essentially means everything goes on the same partition, which for the scenario in question was exactly what we wanted. Not everything needs to be hyper-scalable, and usually there’s an amount of overhead associated with making things so. In a demanding SLA sort of environment an extra hop to a new physical partition can mean the difference between getting paid or not.
