 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.

 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.

 # From Stream to Lake: Hands-On with Fluss Tiering into Paimon on Minio
 
 Fluss stores historical data in a lakehouse storage layer while keeping 
real-time data in the Fluss server. Its built-in tiering service continuously 
moves fresh events into the lakehouse, allowing various query engines to 
analyze both hot and cold data. The real magic happens with Fluss's union-read 
capability, which lets Flink jobs seamlessly query both the Fluss cluster and 
the lakehouse for truly integrated real-time processing.

 In this hands-on tutorial, we'll walk you through setting up a local Fluss 
lakehouse environment, running some practical data operations, and getting 
first-hand experience with the complete Fluss lakehouse architecture. By the 
end, you'll have a working environment for experimenting with Fluss's powerful

format on **Minio** as the storage backend. Let's get started:

 # DataStream API
 ## Overview
 The Fluss DataStream Connector for Apache Flink provides a Flink DataStream 
source implementation for reading data from Fluss tables and a Flink DataStream 
sink implementation for writing data to Fluss tables. It allows you to 
seamlessly integrate Fluss tables with Flink's DataStream API, enabling you to 
process data from Fluss in your Flink applications.

 # Logging
 
 All Fluss processes(CoordinatorServer/TabletServer) create a log text file 
that contains messages for various events happening in that process. These logs 
provide deep insights into the inner workings of Fluss, and can be used to 
detect problems (in the form of WARN/ERROR messages) and can help in debugging 
them.

 # TTL
 
 Fluss supports TTL for data by setting the TTL attribute for tables with 
`'table.log.ttl' = '<duration>'` (default is 7 days). Fluss can periodically 
and automatically check for and clean up expired data in the table.

 # Versioned Merge Engine
 
 The **Versioned Merge Engine** enables data updates based on version numbers 
or event timestamps. It ensures that only the row with the highest version 
number (or event timestamp) for a given primary key is retained. This mechanism 
is particularly useful for deduplicating or merging out-of-order data while 
guaranteeing eventual consistency with the upstream source.
