NFOlux: The Next-Gen Data Streaming Platform

Getting Started with NFOlux: A Practical Guide

What is NFOlux?

NFOlux is a high-performance data streaming platform designed for real-time ingestion, processing, and delivery of event-driven data. It combines low-latency transport, scalable storage, and built-in stream processing primitives so teams can build analytics, pipelines, and event-driven apps with minimal operational overhead.

Why choose NFOlux?

• Low latency: Optimized for sub-second end-to-end delivery.
• Scalability: Horizontally scales across clusters without downtime.
• Fault tolerance: Automatic replication and recovery ensure durability.
• Integrated processing: Native windowing, joins, and stateful operators reduce external dependencies.
• Cost efficiency: Tiered storage and compact serialization lower long-term costs.

Core concepts

• Stream: An append-only sequence of events (records) identified by a topic name.
• Producer: Client or service that publishes events to a stream.
• Consumer: Client or service that subscribes to one or more streams to read events.
• Partition: A shard of a stream that allows parallelism; ordering is guaranteed per partition.
• Offset: Position marker within a partition used for checkpointing and replay.
• Retention: Policy controlling how long data is stored (time- or size-based).
• Stateful operator: Processing unit that maintains local state across events for aggregations, joins, and windows.

Quick architecture overview

NFOlux clusters consist of broker nodes that accept writes and serve reads, a controller that manages metadata and partitioning, and worker nodes that run stream processing jobs. Clients connect via a lightweight SDK supporting at-least-once and exactly-once semantics depending on configuration.

Setup and installation (assumed defaults)

1. Prerequisites: Linux server (Ubuntu 22.04 LTS), Docker 24+, Java 17+.
2. Single-node dev with Docker Compose:
   • Clone the NFOlux quickstart repo:

     Code
     Copy CodeCopied
     git clone https://example.com/nfolux-quickstart.git
     cd nfolux-quickstart docker compose up -d 

   • Wait until the broker and controller services show healthy status.
3. Verify with CLI:

   Code
   Copy CodeCopied
   nfolux-cli clusters list nfolux-cli topics create events –partitions 4 –retention 72h nfolux-cli topics list 

Basic workflow — produce, process, consume

1. Produce (Python SDK example):

   python
   Copy CodeCopied
   from nfolux import Producer p = Producer(endpoint=“localhost:9092”, topic=“events”)
   p.send({“userid”: 123, “action”: “click”, “ts”: 1670000000})
   p.flush()
   

2. Process — simple rolling count (Node.js SDK):

   const { Stream } = require(‘nfolux’);
   const stream = new Stream(‘events’).window({type:‘tumbling’, size:60000});
   stream.aggregate((state, event) => {
   state.count = (state.count || 0) + 1;
     return state;
   }).sink(‘counts’);
   

3. Consume (Java consumer):

   java
   Copy CodeCopied
   Consumer<String> c = new Consumer<>(“events”, “group-1”);
   c.onMessage(record -> {
     System.out.println(record.value());
     c.commit(record.offset());
   });
   c.start();
