In cooperation with the [Hamburg C# and .NET User Group Meetup](https://www.meetup.com/hamburg-c-net-meetup/) & [Microsoft Data Platform Community Hamburg](https://www.meetup.com/hamburger-ms-sql-server-usergroup-by-pass-deutschland-e-v), we invite you to the following Meetup in the City Center of Hamburg:

Join us for an evening of technical talks covering data processing and database performance optimization.

**Schedule:**

* 18:00 - Doors open
* 18:10 - Welcome
* 18:15 - Talks begin

**Talk 1: Rethinking Legacy Systems - Data Change Processing with Project Drasi**
Janek Fellien introduces Project [Drasi](https://drasi.io/), a new open source project from Microsoft that brings Complex Event Processing concepts to legacy systems. How do you detect and react to data changes in existing software? While new systems can use Event Sourcing or custom solutions, legacy systems need different approaches. Janek will show how Drasi can help transform or integrate a monolithic legacy system into a microservices architecture.

**Talk 2: Entity Framework Seems to Like PostgreSQL More Than SQL Server**
Sascha Lorenz presents a short talk on a surprising finding: Microsoft's preferred ORM often runs more efficiently on PostgreSQL than on SQL Server. We'll examine why PostgreSQL sometimes optimizes EF workloads more effectively, compare execution plans, and discuss which index strategies make the difference.
