Music Streaming (Rust, Redis, PostgreSQL, Boto3, React, TypeScript) overview

A music streaming backend optimized for low-latency audio delivery and catalog management. Rust powers the audio serving layer with zero-copy byte range responses for adaptive bitrate streaming, achieving sub-millisecond response times. PostgreSQL stores the music catalog, user playlists, listening history, and royalty accounting records. Redis manages session state, playback queues, and real-time listener counts for popularity rankings. Boto3 interfaces with cloud object storage for the audio file archive with intelligent tiering. React delivers the web player with gapless playback, queue management, and social sharing. The tradeoff is the complexity of royalty calculation accuracy and the cost of maintaining multiple audio quality tiers.
