Is Redis used to store auto-incrementing IDs for databases

I am planning on using Redis to generate and store autoincrementing IDs that I will use as primary key fields in MongoDB.

Is this a good idea given the resiliency and durability of Redis. I am worried that if Redis goes down, I might have to deal with duplicate key issues in MongoDB.

I'm planning on implementing Redis using the Append Only File option, and performing an fsync every time a new command is appended to the AOF. It will be slower but more durable.

I am planning on sharding MongoDB in the future and would like to have the IDs be sequential instead of of using Mongo's internal time based IDs.

After doing some more research and watching the training videos on 10gen, I see that the approach to use sequential IDs is flawed, so I will not use Redis in this fashion.

Might work, but if that is your only use for redis, seems like a bunch of complexity for something that is already available right in mongodb:
