Hey @David_Dabbs - We do support uuidv7 database keys and partitioning in Lakebase PostgreSQL via pg_uuidv7  and Databricks SQL functions. There are some limitations when it comes to clustering and column generation. 

As for Python 3.1.4 - this is an outdated minor release, and modern Databricks runtimes target versions 3.10-3.12 range. Are you inquiring about "3.11.4"? If so, Python 3.11.4 will not land in a Databricks Runtime LTS. Instead, 15.4 LTS already standardizes on Python 3.11.11, and newer LTS lines use Python 3.12.3.

I hope this helps!
