Question

I have a simple question. In MongoDB if a have a document with the list field, does MongoDB gurantee the ordering of the values within the list.

Note: I don’t care about the ordering of actual documents.

i.e. If I insert

{
    something: somevalue,
    alist: [1,2,3,a,s,d,f]
}

will the value of alist always be:

[1,2,3,a,s,d,f]

and not

[2,1,3,a,s,d,f] or
[1,2,3,a,s,f,d] or
...
[1,2,a,3,s,d,f] ..etc

Thanks,
Vackar

Answer 1

Yes, the array order will remain consistent as the record(s) isn’t updated.
