Compare UUIDv4 vs UUIDv7

In this video I'm doing "magic" binary search. This search fallbacks to linear search when the number of tuples is small. Typically this is done to reduce number of branch mispredictions, but it's rather toy feature here. It's taken only for example.

On November 13th, we publicly launched Filecoin Station, a desktop app enabling everybody to participate in the Filecoin economy and earn FIL for contributing their spare computing resources & network bandwidth. (You can download the app here: https://www.filstation.app). The launch was a success, and our network grew from ~50 to more than ~1500 nodes in a few days. As of today, we have 4000 nodes running. We quickly discovered that our database was having a hard time keeping up with the increased load.
