Using UUID for uniqueId

HI all

If i use the UUID like a uniqueId in the future if i break my index in
shards, i will have problems? The UUID generation could generate the same
UUID in differents machines?

Thanks

I would say that this is highly unlikely, but you would need to pay attention to how they are generated, this would be a good place to start:
