Is it a good practice to use the OID value (anInteger) as an "external" identifier of your domain object? ... I like OID/UUIDs, and I don't want to duplicate that logic in my app.
I think for your purpose OID will be fine but I'm not sure. I use UUIDs. You can instruct mongo to use a UUID instead of an OID. Works flawlessly.
How do you do that? Because OID's are a BSON native artifact, efficient in terms of storage and lookup (a 12 byte integer in the end...) Is there a way to have an smaller UUID? more like the first eight chars of a Git commit or similar... Regards, Esteban A. Maringolo
