Identifying users/content by 64 bit Int (like Twitter) vs. 128 bit UUID (string) vs. 64 bit random string? Isn't 64 bit Int or random string far more efficient?

I can;t speak for others, I use all 3:

  • sequential ids for local database primary keys
  • UUID for distribution
  • random short id with collision checking for ephemeral things

They are all fine and all have their pros and cons. There is no one true way to make ids.
