And its reader allows you to take your data just about anywhere. But the reader can be painfully slow when you've got a lot of data to crunch (like when you're serializing to a database). Nippy is a mature, high-performance drop-in alternative to the reader . It is used at scale by Carmine, Faraday, PigPen, Onyx, XTDB, Datalevin, and others. Why Nippy? - Small, simple pure-Clojure library - Terrific performance : the best for Clojure that I'm aware of - Comprehensive support for all standard data types - Easily extendable to custom data types - Robust test suite incl. coverage of every supported type - Mature and widely used in production for 12+ years - Optional auto fallback to Java Serializable for safe types - Optional auto fallback to Clojure Reader (including tagged literals) - Optional smart compression with LZ4 or Zstandard - Optional encryption with AES128 - Tools for easy + robust integration into 3rd-party libraries , etc. - Powerful thaw transducer for flexible data inspection and transformation Quick example Nippy's super easy to use: See the wiki for more. Operational considerations Data longevity Nippy is widely used to store long-lived data and promises (as always) that data serialized ","default_branch":null,"files":null,"tree":[],"storefront":"/r/taoensso","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/taoensso/nippy/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
