Jarvy is a fast, cross-platform CLI that installs and manages developer tools across macOS and Linux.
Documentation
//! kafka - Apache Kafka distributed event streaming platform
//!
//! Apache Kafka itself — broker, ZooKeeper (legacy) / KRaft (modern)
//! controller, and the bundled CLI scripts (`kafka-console-producer`,
//! `kafka-console-consumer`, `kafka-topics`, etc.). Most real-world
//! Kafka work uses lighter CLIs (`kcat`, `rpk`, `kaf`) for everyday
//! pub/sub; install this when you need the full broker for local
//! development or want the official admin scripts.
//!
//! The `command:` is `kafka-topics` (one of the bundled scripts) —
//! `kafka` itself isn't a binary, the distribution exposes its
//! functionality through ~30 separate scripts. Picking
//! `kafka-topics` because it's the most-invoked one.
//!
//! Note: drift detection runs `kafka-topics --version`; broker-only
//! installs without the bundled scripts will register as missing.
