UUID as primary key?

Problems with an auto incrementing key

  1. IDs are usually exposed
    • So if someone wants to know how many users you have, they just have to create a new user
  2. If you're monkeying in the db, you can't accidentally delete a row in another table

Why not a UUID

  • isn't this bad for cluster indexes?
  • you could use a UUID v1
    • that would expose a date
