How to store information hierarchically in python?

Python

Are there libraries for working with a hierarchical database in Python?
the goal is
1. to store huge amounts of data
2. a large number of simultaneous connections to the database
3. a large frequency of data updates

after receiving the metrics, an understanding is built on how to store and give it all away
, so it is unlikely that anyone will answer this question and such a formulation
