Review Comment:
   @michael-s-molina I've reverted the PR back to my initial implementation 
which leverages the `connection` parameter. It states that it provides a handle 
into the current transaction, yet we're likely over committing, i.e., there 
should only be one commit per unit of work. I'm not sure what happens if you 
close the session without committing.  Maybe we using the connection wrongly.
