I. Introduction
Redis is an open-source log-type database written in ansi c language that supports Network, memory persistence, and high-performance key-value. It also provides APIs in multiple languages. Speaking of the Key-Value database NoSQL database, you can think of MongoDB.Similar to Memcached, Memcached supports more storage

Redis Cache Set usesIn Redis, we can look at a set type as an unordered character set, and like the list type, we can also perform actions such as adding, deleting, or determining whether an element exists on that type of data value. It should be explained that the time complexity of these operations is O (1), that is, the constant time to complete the operation. The maximum number of elements a set can con
Since the built-in GUI of Unity is not powerful in both development efficiency and operation efficiency, many GUI plug-ins are derived. It is worth considering what plug-ins should be selected.
Since it is an evaluation, there will be a lot of subjective consciousness, which is not necessarily the basis for choice. For example, I am used to using NGUI plug-ins, so no matter what you say about NGUI, it canno

Original: Redis Advanced Practice How to install Redis on a Windows systemI. Introduction to RedisRedis is a key-value storage system. Similar to memcached, it supports storing more value types, including string (string), list (linked list), set (set), Zset (sorted set-ordered collection), and hash (hash type). These data types support Push/pop, Add/remove, and intersection-set and difference sets, and rich

RedisIt is a memory-based high-performance Key-value database that stores data in the memory and regularly refreshes the data to the disk. This is a concern for high read/write efficiency. It supports various data structures, such as stirng, hashes, list, set, and sorted sets.
