 Earlier this year at Flink Forward 2024 Berlin we [announced Fluss](https://www.ververica.com/blog/introducing-fluss) and today we are thrilled to announce open-sourcing the project.
 Fluss is a **streaming storage system** designed to power real-time analytics. It aspires to change how organizations approach real-time data by acting as the **real-time data layer** for the Lakehouse. 
 Its cutting-edge design enables businesses to achieve **sub-second latency**, **high throughput**, and **cost efficiency** for data analytics, making it the ideal solution for modern data-driven applications.

 We have discussed the challenges of using Kafka for real-time analytics in our previous [blog post](/blog/why-fluss/).
 Today, we are excited to introduce Fluss, a cutting-edge streaming storage system designed to power real-time analytics.
 We are going to explore Fluss's architecture, design principles, key features, and how it addresses the challenges of using Kafka for real-time analytics.
