Description

As per Mongo Isolation guarantees

Reads may miss matching documents that are updated during the course of the read operation.

This can result in some scenarios where query performed might miss out on some documents if that document gets modified while query is being execute.

Aim of this task is to analyze the kind of queries current Oak uses with Mongo and see if current support from Mongo is sufficient for our needs
