The author discusses the 7th principle of the Redis Manifesto, which emphasizes the importance of simplicity and avoiding unnecessary complexity. The author shares a personal experience where they helped someone improve their code using Redis, and then explores the idea of implementing a `LSCAN` command for scanning lists in Redis. They discuss various approaches to duplicating large lists, including using Lua scripts, LRANGE, SORT, DUMP, and RESTORE commands, and evaluate their performance. The author also touches on the idea of creating a custom client that can load data into Redis quickly by preprocessing and injecting final serializations directly, but notes the potential risks and challenges involved.
