## What is Fluss?
Fluss is a streaming storage built for real-time analytics which can serve as the real-time data layer for Lakehouse architectures.
It bridges the gap between **data streaming** and **data Lakehouse** by enabling low-latency, high-throughput data ingestion and processing while seamlessly integrating with popular compute engines like **Apache Flink**, while Apache Spark, and StarRocks are coming soon.
**Fluss (German: river, pronounced `/flus/`)** enables streaming data continuously converging, distributing and flowing into lakes, like a river 🌊
# Features
- **Sub-Second Latency**: Low-latency streaming reads/writes optimized for real-time applications with Apache Flink.
- **Columnar Stream**: 10x improvement in streaming read performance with efficient pushdown projections.
- **Streaming & Lakehouse Unification**: Unified data streaming and Lakehouse with low latencies for powerful analytics.
- **Real-Time Updates**: Cost-efficient partial updates for large-scale data without expensive join operations.
- **Changelog Generation**: Complete changelogs for streaming processors, streamlining analytics workflows.
- **Lookup Queries**: Ultra-high QPS for primary key lookups, enabling efficient dimension table serving.
## Building
Prerequisites for building Fluss:
- Unix-like environment (we use Linux, Mac OS X, Cygwin, WSL)
- Git
- Maven (we require version >= 3.8.6)
- Java 8 or 11
```bash
git clone https://github.com/alibaba/fluss.git
cd fluss
./mvnw clean package -DskipTests
```
Fluss is now installed in `build-target`. The build command uses Maven Wrapper (`mvnw`) which ensures the correct Maven version is used.
