The goal of this is to reduce DB queries? Why not just queue up / batch writes? What benefits does this provide over application side batching of the event.

EvenReduce assumes there are no other systems interacting with the DB state (by using the old state that the current system saw). If there are no other systems, simple batching would work fine.

All your assumptions are wrong. Please read the other comments here or at least the readme of the repository. I will happily answer all ongoing questions you have afterwards.
