## What it is
JStorm was Alibaba's enterprise stream processing engine, a Java-based distributed real-time computation framework compatible with Apache Storm's programming model. The project was donated to the Apache Software Foundation and merged into Apache Storm; this repository is archived and read-only.

## Use cases
- process high-throughput real-time data streams
- run Storm-compatible topologies on a JVM cluster
- build real-time analytics pipelines
- migrate legacy JStorm jobs to Apache Storm
- distributed real-time event computation at scale

## When to choose
- you maintain an existing JStorm deployment and need reference material
- you want to study the architecture that was merged into Apache Storm

## When to avoid
- starting any new stream processing project - use Apache Storm, Flink, or Spark Streaming instead
- you need bug fixes, new features, or community support - the repo is archived and read-only
- you expect the linked homepage to be relevant - it is squatted by unrelated gambling content
