 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.

 The unification of Lakehouse and streaming storage represents a major trend in the future development of modern data lakes and streaming storage systems. Designed specifically for real-time analytics, Fluss has embraced a unified Streaming and Lakehouse architecture from its inception, enabling seamless integration into existing Lakehouse architectures. 
 
 Fluss is designed to address the demands of real-time analytics with the following key capabilities:

 On June 5th, Fluss, the next-generation streaming storage project open-sourced and donated by Alibaba, successfully passed the [vote](https://lists.apache.org/thread/mnol4wxovpz6klt196d3x239t4mp6z5o) and officially became an incubator project of the Apache Software Foundation (ASF). This marks a significant milestone in the development of the Fluss community, symbolizing that the project has entered a new phase that is more open,
 neutral, and standardized. Moving forward, Fluss will leverage the ASF ecosystem to accelerate the building of a global developer community, continuously driving innovation and adoption of next-generation real-time data infrastructure.
