Atomic Operators Inside a Session

What are the repercussions of performing atomic operations such as $inc within a transaction? For instance, if I increment by 10 and then roll back the transaction, will it revert to the session’s initial value or will the transaction subtract ten?

Probably

Derek_Menendez1:

revert to the session’s initial value

if the other would happen (or if subtract 10 could potentially give a different result) it would means your data was by some other process. That would void the whole reason of transactions.

If my data is inside a transaction I expect any other writers not be able to update this data during my transaction.
