DocumentDB - Does a newer session token guarantee reading back older writes?

Question

Let's assume I have two documents in the same collection/partition, both at "version 1": A1, B1.

I update A1 -> A2, the write operation returns a session token SA.
Using SA to read document A will guarantee I get version A2.

Now I update B1 -> B2, and get a new session token SB. Using SB to read document B will guarantee I get version B2.

My question is: does using token SB guarantee I can see older writes as well?
I.e. will reading A with token SB always get me A2 ?

Answer 1

Yes. In your case SB > SA and hence it will ensure latest version of A.
