Query Optimization
I would like to be able to push all elements of an array field into a new field. So, in a $group, I could do a $push or $addToSet of a field that is an array field and the resulting field would be an array of the elements instead of an array of arrays.
Seems like the $each operator in update is the solution if added to aggregations.
