Don't use UUIDs as primary keys

[scytherswings]

Stop using UUIDs as primary keys. We need to implement friendlyId instead. UUIDs inflate indexes which slows them down. If we need pretty, readable URLs we should use a slug instead of the PK anyway. Also integer keys scale better and overall are less data to join on in a large database (think string sorting is way more expensive than integer sorting, for example). Also we don't have random inserts coming from outside sources so we don't need the uniqueness anyway.

After reading more, this could be a thing that also doesn't matter. I haven't figure out if it's important or not.

Nope, not changing.
