global auto-incrementing field in MongoDb

Question

Is there a way to create a globally auto-incrementing value in a collection?

Perforce has the concept of a changelist# that can be a powerful feature for stateless updat

Answer 1

The MongoDB docs have a listing for auto-incrementing fields. In general it is bad practice, but this could work for the functionality you seek.

That stated, I have also seen people use "timestamps" for the last updated time. This may satisfy your requirements.

Likewise, if this is a really key feature, you may want to look at Riak's MVCC which seems closest to what you want.
