Show HN: EventReduce – Algorithm to optimise db queries that run multiple times

Hi, Daniel here. About a year ago, I made this algorithm called EventReduce. It is able to optimize database queries that run multiple times (aka Realtime-Queries or Live-Queries). Before making EventReduce, I scouted over about 2 years if something like this already exists but couldnt find something similar other then MongoDBs OPLOG_DRIVER. After finishing EventReduce last year I added it to my little side project database, RxDB[1] where it is sucessfully in use over the last year. Also I already made a hackernews post [2] with mixed comments about how this can work and when this is usefull. So now I am here again with the goal to get some feedback of people who try out EventReduce on top of their database.
