Marten is a .NET Transactional Document DB and Event Store on PostgreSQL. Every dotnet dev should try it as an alternative ef-core, not everything needs a full blown ORM.

Awesome walk-through. Any plan to give us a run-down on EventstoreDB ?

is there an option to filter events before projection by some argument?

It’s look like there is a lot of reflection underneath. I’m right?

No it uses Roslyn Generators, Google for Lamar

You didn't explain the differences between self-aggregating projection and projector..., now I have to google for this info... 😠...., haha... jk... nice intro to marten!

Cheers, I’m pretty good at answering comments. For anyone actually wondering self aggregate is a projection which builds it self. projector is component which appends events on to a projection. In self aggregates you don’t see the projection being passed as an argument to the Apply functions.
