The writes are not tunneled somehow through this algorithm. You still use the database like your normally would do. So the consistency is not affected. Also this is an open source project, not something I want to sell you. Feel free to make a PR/issue with any open topics that are not mentioned in the docs.

They better be making an informed decision whether your solution suits their needs.

  You have to provide the events by yourself. See EventReduce as a simple function that can do oldResults+Event=newResults. And yes, you should always do testings before you use open source stuff. There is no warranty use it on your own risk.

    OK, so you don't "tunnel writes through" EventReduce, you "tee" them to EventReduce. Anyway, to maintain consistency, you have to limit yourself to one process of your app. No sharding, load-balancing etc. This is significant limitation, and it's not obvious. I encourage you to mention it in README.md.

      I encourage you to read the readme and check out the demo. EventReduce is nothing magically drills out your database and affects the consistency of your write-accesses. It is a simple algorithm that is implemented as a function with two inputs and one output.
