It definitely wouldn't be hard to create this function. You could add  
it to ConnectionPool, but a subclass would work equally well.

Just take a look at how runOperation works, and create a similar  
function, runOperationMany(trans, *args, **kwargs). This should call  
runInteraction and pass your second function _runOperationMany(trans,  
*args, **kwargs) which uses the `trans` as the cursor object.

Transaction instances like that automatically inherit all the  
attributes of the base cursor class in your particular driver, so you  
should be able to call executemany() without a problem.

Hope that helps,
