Real applications,
built with Storm.

The same movie browser, implemented three times on the public IMDB dataset, so you can compare stacks and explore what idiomatic Storm looks like in a real project: immutable entities, metamodel-based queries, transactions, schema validation, and a full test suite. Clone one and run it with Docker and Gradle.
