使用 Redis?編程

Programming with Redis

• 過期：Redis?允許為每一個鍵設置一個不同的存活時間，以便?這個鍵在過期時會自動移除。Expires: Redis allows to set a time to live different for every key so that the key will be automatically removed from the server when it expires.
• Redis?作為一個最近使用原則緩存：Redis as an LRU cache: How to configure and use Redis as a cache with a fixed amount of memory and auto eviction of keys.
• Redis?事務：Redis transactions: It is possible to group commands together so that they are executed as a single transaction.

Redis?模塊接口 Redis modules API

• Introduction to Redis modules. A good place to start learing about Redis 4.0 modules programming.
• Implementing native data types. Modules scan implement new data types (data structures and more) that look like built-in data types. This documentation covers the API to do so.
• Blocking operations?with modules. This is still an experimental API, but a very powerful one to write commands that can block the client (without blocking Redis) and can execute tasks in other threads.
• Redis modules API reference. Directly generated from the top comments in the source code inside?src/module.c. Contains many low level details about API usage.
