Does Datastore put requests to a Queue or do they get processed at the same time?

[MeteorxBG]

I am intending on making a unique ascending ordered ID system for servers(I do know that they aldready posses a uid but the way i want it makes it easier for me to work with).

I wish to know if Datastores put requests into a queue or if they get proccessed at the same time? Since this is going to be a Universe Wide thing i am wondering 2 different servers try to get into the same index.

If they get put into a queue then there shouldn’t be a problem but if that is not the case i am going to have to look for another way like generating the number through serverId or using GUID(which is worse for my case).

I’m pretty sure that DataStore requests do get placed into a queue (but I’m not entirely sure), hence this warning when you try to save too much at once:
DataStore request was added to queue. If queue fills, further requests will be dropped. Key: (key)
