More about MongoDB id
--------------------------------

- it's a 12 byte value
- first 4 bytes is a timestamp (it means in our documents we don't need to have a 'created_at' field)
- next 3 bytes is a machine identifier
- next 2 bytes a process id
- next 3 bytes a counter (this is similar to what MySQL would do with an autocomplete field)
