Berlin Systems Group

​​A Meetup for all low level systems enthusiasts in Berlin. If you’re interested in how Databases, Distributed Systems and Compilers work, this Meetup is the place for you!

​Guests:

• ​Yingjun Wu, CEO, RisingWave Labs

  • ​Title: Streaming Analytics in the Cloud: Not Your Father's Streaming SQL Engine!

    • ​Abstract:

      • ​How do you query streaming data in real time? Use streaming SQL engine! It sounds straightforward, right? However, when it comes to handling schema changes, dynamic scaling, high availability, and complex streaming joins, the challenges become apparent. The root cause often lies in how internal states are managed in these systems.

      • ​In this talk, I will introduce RisingWave, a scalable streaming database that utilizes S3 as its primary storage. By decoupling compute from storage, RisingWave enables independent scaling of these components. From underlying technology to real-world scenarios, I will illustrate how RisingWave supports heavy traffic workloads in enterprise-grade production environments.

• ​Stephan Ewen, CEO, Restate.dev

  • ​Building Restate.dev, an event-driven system from the ground up for durable execution and transactional workflows, and how that differs from an event-driven system for analytics (@ApacheFlink).

  • ​Restate is a new project building from the ground up a deeply integrated runtime for fast durable execution, durable promises, virtual objects, and other primitives to more easily build resilient distributed applications and services. We'll look at Restate's architecture and its design decisions, and draw parallels and differences with our previous work building Apache Flink.

​We will update the location shortly.
