I think there is some nuance needed here. If you ask support to partition your bucket then they will be a bit annoying if you ask for specific partition points and the first part of the prefix is not randomised. They tried to push me to refactor the bucket first to randomise the beginning of the prefix, but eventually they did it.
The auto partitioning is different. It can isolate hot prefixes on its own and can intelligently pick the partition points. Problem is the process is slow and you can be throttled for more than a day before it kicks in.
