How to generate a time-ordered uid in Python?

Is this possible? I've heard Cassandra has something similar : https://datastax.github.io/python-driver/api/cassandra/util.html

I have been using a ISO timestamp concatenated with a uuid4, but that ended up way too large (58 characters) and probably overkill.

Keeping a sequential number doesn't work in my context (DynamoDB NoSQL)

Worth noticing that for my application it doesn't matter if items created in batch/same second are in a random order, as long as the uid don't collapse.

I have no specific restriction on maximum length, ideally I would like to see the different collision chance for different lengths, but it needs to be smaller than 58 (my original attempt)

This is to use with DynamoDB(NoSQL Database) as Sort-key
