cuid as partition key

[kjmiller1]

Due to the c{timestamp}... structure, I have concerns about "todays" items creating a hot spot in a distributed data store for my use-case (long history of items, todays items are used heavily, using aws DynamoDB).

Thoughts on the validity of my concern?

Most distributed storage systems allow you to create your own partitioning hash function. I would give it a try, and if it does indeed create a hotspot, swap out the hash function to solve it.
