Add UUIDv7 as default record primary key

[ezekg]

Should improve performance and risk in using batch operations like find_each using the default of sorting by primary key.

Prereqs

• Talk to customers and make sure this won't be a breaking change, e.g. if a customer is expecting UUIDv4s, this would break that expectation — even if we have always reserved the right to change the format of new resource identifiers.

[seuros]

You can use ulid, it cleaner and you can prefix it.
Here is a gem i build for it : https://github.com/seuros/activerecord-ulid

[ezekg]

@seuros our Postgres primary keys are UUIDs, so that won't work. Changing primary key type is infeasible.

In that case, yes.
