What is the difference between swoole and redis

Difference: 1. Redis is a "key-value" storage system written by "Salvatore Sanfilippo", while Swoole is PHP's asynchronous, parallel, high-performance network communication engine; 2. Redis provides multiple language APIs , Swoole provides asynchronous multi-threaded server in PHP language.

What is the difference between swoole and redis

Swoole is PHP's asynchronous, parallel, high-performance network communication engine. It is written in pure C language and provides asynchronous multi-threaded server of PHP language, asynchronous TCP/UDP network client, asynchronous MySQL, asynchronous Redis, database connection pool, AsyncTask , message queue, millisecond timer, asynchronous file reading and writing, asynchronous DNS query.

REmote DIctionary Server (Redis) is a key-value storage system written by Salvatore Sanfilippo.

swoole

Swoole has built-in Http/WebSocket server/client and Http2.0 server.

Swoole can be widely used in the Internet, mobile communications, enterprise software, online games, Internet of Things, Internet of Vehicles, smart homes and other fields. Using PHP Swoole as a network communication framework can greatly improve the efficiency of enterprise IT R&D teams and focus more on developing innovative products.

Swoole has a built-in asynchronous non-blocking, multi-threaded network IO server at the bottom. PHP programmers only need to handle event callbacks and do not need to care about the underlying layer. Unlike fully asynchronous frameworks such as Nginx/Tornado/Node.js, Swoole supports both fully asynchronous and synchronous.

redis

Redis is an open source log-type, Key- Value database and provides APIs in multiple languages. (Recommended learning: swoole video tutorial)

It is often called a data structure server, because the value can be a string (String), a hash (Hash), a list (list), a collection (sets) ) and ordered sets (sorted sets) and other types.

Redis is a high-performance key-value database. The emergence of redis has largely compensated for the shortcomings of key/value storage such as memcached, and can play a very good supplementary role to relational databases in some situations.

It provides Java, C/C, C#, PHP, JavaScript, Perl, Object-C, Python, Ruby, Erlang and other clients, which is very convenient to use.

Redis supports master-slave synchronization. Data can be synchronized from the master server to any number of slave servers, and the slave server can be a master server associated with other slave servers.

Implementation of Swoole

Swoole is written in pure C and does not rely on other third-party libraries.

swoole does not use libevent, so there is no need to install libevent

swoole does not rely on PHP's stream/sockets/pcntl/posix/sysvmsg and other extensions
