Redis creator Salvatore Sanfilippo has proposed adding native array support to Redis through a new pull request, introducing 18 new array-specific commands. The most notable feature is ARGREP, which enables server-side regex pattern matching on array elements using the TRE regex library. A web-based playground has been created to experiment with these new array commands using WebAssembly-compiled Redis in the browser.
Background
Redis is an open-source, in-memory data structure store used as a database, cache, and message broker. While it supports various data types like strings, hashes, lists, and sets, native array support has been a long-requested feature in the Redis community.
