Question

Using MongoDB C# Driver (official form 10gen), I’m doing the following code:

using (database.RequestStart()) {    
    collection.Save(object);    
}

I would want to know how to stop the request and rollback the existing performed operations after the RequestStart()method.

Thanks in advance, guys!

Answer 1

Well, I searched across the web and found these methods only increase connection performance, but doesn’t stores any operation.

The concept of MongoDB operations are performed with a single-by-single operation.

The RequestStart() method only gets the current connection state for reusing it. If no existing connection are open, it opens a new connection and tell to driver that all the following operations – until the RequestDone() method is called – will use the current opened connection.

In other side, MongoDB have the capability to do two-phase commits, which are, in our “SQL concept”, a transaction-like pattern. In this case, the MongoDB C# Driver needs to implement this pattern, or we can do it ourselves developing command adapters.
