Storm
In plain terms
A system for real-time stream processing.
Going deeper
Apache Storm processes unbounded streams of data with low latency, computing on events as they arrive. It targets real-time analytics.
Under the hood
Topologies of spouts and bolts process tuples continuously; largely overtaken by Spark Streaming and Flink.
Examples
Real-time analytics, stream processing, event handling, low-latency pipelines.
Think of it like...
Like an assembly line that processes items the instant they appear, never waiting.
