Redis?的作者antirez(Salvatore Sanfilippo)同学发表了一篇名为Redis?宣言Redis Manifesto)的文章,文中列举了Redis 的七个原则,以向大家阐明Redis 的思想

  1. Redis 是一个操作数据结构的语言工具,它提供基于TCP的协议以操作丰富的数据结构。在Redis中,数据结构这个词的意义不仅表示在某种数据结构上的操作,更包括了结构本身及这些操作的时间空间复杂度。
  2. Redis 定位于一个内存数据库,正是由于内存的快速访问特性,才使得Redis能够有如此高的性能,才使得Redis能够轻松处理大量复杂的数据结构,Redis会尝试其它的存储方面的选择,但是永远不会改变它是一个内存数据库的角色。
  3. Redis 使用基础的API操作基础的数据结构,Redis的API与数据结构一样,都是一些最基础的元素,你几乎可以将任何信息交互使用此API格式表示。作者调侃说,如果有其它非人类的智能生物存在,他们也能理解Redis的API。因为它是如此的基础。
  4. Redis 有着诗一般优美的代码,经常有一些不太了解Redis 原则的人会建议Redis采用一些其它人的代码,以实现一些Redis 未实现的功能,但这对我们来说就像是非要给《红楼梦》接上后四十回一样。(作者此处用了莎士比亚的比喻)
  5. Redis 始终避免复杂化,我们认为设计一个系统的本质,就是与复杂化作战。我们不会为了一个小功能而往源码里添加上千行代码,解决复杂问题的方法就是让复杂问题永远不要提复杂的问题。
  6. Redis 支持两个层成的API,第一个层面包含部分操作API,但它支持用于分布式环境下的Redis。第二个层面的API支持更复杂的multi-key操作。它们各有所长,但是我们不会推出两者都支持的API,但我们希望能够提供实例间数据迁移的命令,并执行multi-key操作。
  7. 我们以优化代码为乐,我们相信编码是一件辛苦的工作,唯一对得起这辛苦的就是去享受它。如果我们在编码中失去了乐趣,那最好的解决办法就是停下来。我们决不会选择让Redis不好玩的开发模式。

Golang API caching strategy and optimization Golang API caching strategy and optimization May 07, 2024 pm 02:12 PM

The caching strategy in GolangAPI can improve performance and reduce server load. Commonly used strategies are: LRU, LFU, FIFO and TTL. Optimization techniques include selecting appropriate cache storage, hierarchical caching, invalidation management, and monitoring and tuning. In the practical case, the LRU cache is used to optimize the API for obtaining user information from the database. The data can be quickly retrieved from the cache. Otherwise, the cache can be updated after obtaining it from the database.

Caching mechanism and application practice in PHP development Caching mechanism and application practice in PHP development May 09, 2024 pm 01:30 PM

In PHP development, the caching mechanism improves performance by temporarily storing frequently accessed data in memory or disk, thereby reducing the number of database accesses. Cache types mainly include memory, file and database cache. Caching can be implemented in PHP using built-in functions or third-party libraries, such as cache_get() and Memcache. Common practical applications include caching database query results to optimize query performance and caching page output to speed up rendering. The caching mechanism effectively improves website response speed, enhances user experience and reduces server load.

First you need to set the system language to Simplified Chinese display and restart. Of course, if you have changed the display language to Simplified Chinese before, you can just skip this step. Next, start operating the registry, regedit.exe, directly navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlNlsLanguage in the left navigation bar or the upper address bar, and then modify the InstallLanguage key value and Default key value to 0804 (if you want to change it to English en-us, you need First set the system display language to en-us, restart the system and then change everything to 0409) You must restart the system at this point.

How to use Redis cache in PHP array pagination? How to use Redis cache in PHP array pagination? May 01, 2024 am 10:48 AM

Using Redis cache can greatly optimize the performance of PHP array paging. This can be achieved through the following steps: Install the Redis client. Connect to the Redis server. Create cache data and store each page of data into a Redis hash with the key "page:{page_number}". Get data from cache and avoid expensive operations on large arrays.

1. First, double-click the [This PC] icon on the desktop to open it. 2. Then double-click the left mouse button to enter [C drive]. System files will generally be automatically stored in C drive. 3. Then find the [windows] folder in the C drive and double-click to enter. 4. After entering the [windows] folder, find the [SoftwareDistribution] folder. 5. After entering, find the [download] folder, which contains all win11 download and update files. 6. If we want to delete these files, just delete them directly in this folder.

PHP Redis caching applications and best practices PHP Redis caching applications and best practices May 04, 2024 am 08:33 AM

Redis is a high-performance key-value cache. The PHPRedis extension provides an API to interact with the Redis server. Use the following steps to connect to Redis, store and retrieve data: Connect: Use the Redis classes to connect to the server. Storage: Use the set method to set key-value pairs. Retrieval: Use the get method to obtain the value of the key.
