What it is
Storm is a distributed realtime computation system designed to process large streams of data in real-time. It provides fault-tolerance and scalability, making it suitable for applications that require low-latency processing of continuous data flows.
Storm stands out as a mature, open-source solution for processing large streams of data in real-time with guaranteed message processing and fault-tolerance, making it ideal for scalable applications requiring low-latency.
When it fits — and when it doesn’t
A good fit for
Teams needing a fault-tolerant system for processing large streams of data in real-time.
Projects that require guaranteed message processing with low-latency.
Look elsewhere if
Applications requiring real-time streaming without the need for distributed architecture and scalability.
Small-scale projects where simplicity outweighs the benefits of a distributed system.
Known weaknesses
Each one links to the public issue, changelog or docs page it came from, where we have one.
- 01
Steep learning curve for new users
Storm's architecture and terminology are complex, requiring significant time investment to understand its inner workings.
- 02
Limited language support beyond Java
While Storm provides a core Java API, support for other languages is limited or non-existent, constraining development flexibility.
- 03
Complex setup and configuration
Setting up a Storm cluster requires configuring multiple components including ZooKeeper and Nimbus, which can be error-prone and time-consuming.
- 04
Performance bottlenecks in large-scale deployments
In very large clusters or under heavy load, Storm's performance may degrade due to coordination overhead between nodes.
What it does well
