Amazing, well done. Having used Go for something similar can understand why you chose that for this venture. Wondering if there was anything in particular worked out for you with that decision?

I've been using Go for some time now. I've never programmed with Rust before, and it seemed appropriate to use Go for this project. In my initial prototypes of an event sourcing system that I experimented with last year, I used PHP (yes PHP) with either PostgreSQL or MySQL and a few other things. A major advantage of Go is its backward compatibility, which certainly makes maintenance easier.
