Redis 数组类型交互式体验平台上线
阅读原文· simonwillison.netRedis 加数组类型可能改变很多缓存设计，Simon 这个 WASM playground 是把 PR 变成可试产品的最快路径，后端同学可以直接上手体会 ARGREP 的快乐。
Redis创始人Salvatore Sanfilippo提交了为Redis新增数组数据类型的PR，引入了包括ARCOUNT、ARDEL、ARGREP等在内的18个新命令。其中最引人注目的是ARGREP命令，它利用新集成的TRE正则表达式库，可直接在服务器端对数组值进行正则搜索。目前该功能已在一个分支中实现，开发者Simon Willison借助Claude Code构建了一个交互式在线沙盒，通过运行在浏览器中的WASM版Redis子集，供用户体验这些新命令。Salvatore还撰文详细介绍了在AI辅助下开发此功能的历程。

Salvatore Sanfilippo submitted a PR adding a new data type - arrays - to Redis.
The new commands are ARCOUNT, ARDEL, ARDELRANGE, ARGET, ARGETRANGE, ARGREP, ARINFO, ARINSERT, ARLASTITEMS, ARLEN, ARMGET, ARMSET, ARNEXT, AROP, ARRING, ARSCAN, ARSEEK, ARSET.
The implementation is currently available in a branch, so I had Claude Code for web build this interactive playground for trying out the new commands in a WASM-compiled build of a subset of Redis running in the browser.
The most interesting new command is ARGREP which can run a server-side grep against a range of values in the array using the newly vendored TRE regex library.
Salvatore wrote more about the AI-assisted development process for the array type in Redis array type: short story of a long development.
