**Our Agenda:**

• 6:00pm - 6:15pm: Virtual Mingle and Happy Hour
• 6:15pm - 8:00pm: Introductions & Our featured speaker

**Abstract:**

Marten ([https://martendb.io/](https://martendb.io/)) is an open-source library that enables .Net developers to use the rock-solid Postgresql database as a full-featured event store and document database. In this session I'll show how Marten provides "event sourcing in a box" through its integrated support for capturing event streams, projecting "read-side" views of those same event streams, and full support for storing and querying the projected views. All with one library and database.

We'll start with an obligatory quick start, but move into how to scale an event-sourced application with Marten to very large data sets.

In a conference dedicated to event sourcing, we'll go beyond the basics of event sourcing into Marten's unique abilities like live aggregation and "inline" projections when you need ACID compliance rather than eventual consistency. We'll also look at how Marten helps you deal with concurrency issues during event sourcing.
