Guillaume Endignoux explores how to compress JSON data using the interning design pattern in Rust in a weekend project. The RATP status website’s historical data is used as a case study, with 10 GB of JSON files compressed by a factor of 2000%. The process involves interning strings and arbitrary types like structs, utilizing Rust crates like serde for deserialization. The implementation results in significant memory savings, making it especially useful for handling large JSON datasets efficiently. Endignoux’s detailed explanation and optimization methods showcase the power of Rust for data compression, offering valuable insights for developers dealing with similar challenges.
