Grow with the Flow: How Kotlin Flow Became a Game Changer for our Business | Urs Peter

Kotlin’s Flow is a powerful abstraction with unprecedented potential that revolutionized data exchange of my client in the telecom industry.

This talk will explore this success story with Kotlin Flow as the main actor that powered a groundbreaking streaming application using server-sent events. This application had a disruptive impact both in B2B interactions and internally.

Starting with a crisp and understandable exploration of Kotlin Flow and its brothers StateFlow and SharedFlow, we will live-code the essentials of the game-changing solution step by step. Along the way, we will show off all the crucial capabilities of the Flow family on stage, revealing how all aspects enable you to build a cutting-edge, mission-critical streaming application.

Finally, discover how Flow not only facilitated the development of a game-changing streaming API but also became the cornerstone of our Event-Driven Architecture. This shift allowed us to bypass traditional messaging solutions like Kafka entirely, simplifying our infrastructure and significantly reducing operational overhead.

After this session, you will have tasted the transformative power of Kotlin's Flow and how to leverage it to your benefit so that you, too, can 'Grow with the Flow'!

Tried to return a flow from an api using spring as in the video, but just didn't work... Also I was able to do it with ktor but not so straightforward
