CONTENT ADDRESSABLE STORAGE

Summary from the TLDR Web Dev newsletter

Content Addressable Storage (CAS) uses cryptographic hashes of file content for addressing, making sure that identical content always generates the same hash. The technique solves problems related to browser caching and data duplication. This article goes over a Rust implementation of a CAS system, starting with a simple in-memory store and progressing to a persistent store that optimizes file system layout for performance.
