Stream Forward Barcelona

​One day talking. One day doing. No pitches. No filler.

​Stream Forward is a practitioner conference for the people who actually run Apache Flink® in production. Engineers, architects, and business leaders gather to share what works, what broke, and what became possible with real-time streaming data.

​The conference takes place in a cinema. Talks on the big screen, sound that fills the room, an experience built to match the scale of what's being built. Expect short, dense talks: architecture deep dives alongside boardroom outcomes. No theory without numbers.

​Day 1. The Main Feature
Practitioner talks, real business use cases, architecture deep dives, war stories from production, and a panel discussion. Doors open at 08:30. Talks run 09:00–17:00. Networking with drinks and food follows until 19:00. One ticket, full-day access, lunch included.

​Day 2. X-Stream Lab
Hands-on training guided by Ververica engineers. Small groups, whiteboard sessions, and real code. You leave with a working application and sandbox access that persists for 7 days.
