hi @rkistner , maybe you can answer that. Sorry for a lots of questions, but i'm heavily investigate on Powersync to decide what techstack should our team will use in the next project.

We store the history of changes in MongoDB. That is re-computed from the source database whenever you deploy sync rule changes.

You can see the code for that here: https://github.com/powersync-ja/powersync-service, and a diagram with the architecture for self-hosting is here: https://docs.powersync.com/self-hosting/installation

Our discord is also great for questions like this.
