Several updates on MongoDB library were made to support latest version
With the latest version of Mongo DB we updated the underlying libraries in OTDT to support and respect all given new features if using Mongo DB as state store.
While using Mongo DB as the state store in environments needing to be persistent or high available was working well before our updates, it is specially the complexity of built queries on the one hand and the speed on the other.
At least the last one is much important if using OTDT in a geographical distance (or at least high latency connection) for a high available environment.
We made many, many tests around these updates to ensure the stability of the new libraries.
