Preface: Lua is a powerful, fast, lightweight, embeddable scripting language. So it can work with Geospatial data perfectly.
Technical background: Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache and message broker. In order to achieve its outstanding performance, Redis contains different functions.The Redis Lua interpreter loads seven libraries: base, table, string, math, debug, cjson, and cmsgpack. From performance point of view, CJSON library provides extremely fast JSON manipulation within Lua.
