redis performance test and client connection

Redis performance test

Recommended: redis tutorial

Syntax:

redis-benchmark [option] [option value]
Copy after login

Example

Example 1

The following example executes 1000 requests at the same time to test performance:

$   redis-benchmark -n 1000  -q
Copy after login

ps: Local docker does not support the command temporarily. The result is skipped, please test by yourself.

redis:6379> benchmark -n 1000 -q
(error) ERR unknown command 'benchmark'
Copy after login

Example 2

The host is 127.0.0.1, the port number is 6379, the executed commands are set, lpush, the number of requests is 1000, and the -q parameter is used to allow the results to only display execution per second number of requests.

$ redis-benchmark -h 127.0.0.1 -p 6379 -t set,lpush -n 1000 -q
Copy after login

Performance test parameters

14-IIdle 模式。仅打开 N 个 idle 连接并等待。

Redis 客户端连接

Redis 通过监听一个 TCP 端口或者 Unix socket 的方式来接收来自客户端的连接,当一个连接建立后,Redis 内部会进行以下一些操作:

首先,客户端 socket 会被设置为非阻塞模式,因为 Redis 在网络事件处理上采用的是非阻塞多路复用模型。

然后为这个 socket 设置 TCP_NODELAY 属性,禁用 Nagle 算法

然后创建一个可读的文件事件用于监听这个客户端 socket 的数据发送

最大连接数

redis:6379> config get maxclients
1) "maxclients"
2) "10000"
Copy after login

实例

启动时设置最大连接数为 999

redis-server --maxclients 999
Copy after login

客户端命令

S.N. 命令 描述
1 CLIENT LIST 返回连接到 redis 服务的客户端列表
2 CLIENT SETNAME 设置当前连接的名称
3 CLIENT GETNAME 获取通过 CLIENT SETNAME 命令设置的服务名称
4 CLIENT PAUSE 挂起客户端连接,指定挂起的时间以毫秒计
5 CLIENT KILL 关闭客户端连接

How to build the redis cluster mode How to build the redis cluster mode Apr 10, 2025 pm 10:15 PM

Redis cluster mode deploys Redis instances to multiple servers through sharding, improving scalability and availability. The construction steps are as follows: Create odd Redis instances with different ports; Create 3 sentinel instances, monitor Redis instances and failover; configure sentinel configuration files, add monitoring Redis instance information and failover settings; configure Redis instance configuration files, enable cluster mode and specify the cluster information file path; create nodes.conf file, containing information of each Redis instance; start the cluster, execute the create command to create a cluster and specify the number of replicas; log in to the cluster to execute the CLUSTER INFO command to verify the cluster status; make

How to implement the underlying redis How to implement the underlying redis Apr 10, 2025 pm 07:21 PM

Redis uses hash tables to store data and supports data structures such as strings, lists, hash tables, collections and ordered collections. Redis persists data through snapshots (RDB) and append write-only (AOF) mechanisms. Redis uses master-slave replication to improve data availability. Redis uses a single-threaded event loop to handle connections and commands to ensure data atomicity and consistency. Redis sets the expiration time for the key and uses the lazy delete mechanism to delete the expiration key.

How to read the source code of redis How to read the source code of redis Apr 10, 2025 pm 08:27 PM

The best way to understand Redis source code is to go step by step: get familiar with the basics of Redis. Select a specific module or function as the starting point. Start with the entry point of the module or function and view the code line by line. View the code through the function call chain. Be familiar with the underlying data structures used by Redis. Identify the algorithm used by Redis.

How to read redis queue How to read redis queue Apr 10, 2025 pm 10:12 PM

To read a queue from Redis, you need to get the queue name, read the elements using the LPOP command, and process the empty queue. The specific steps are as follows: Get the queue name: name it with the prefix of "queue:" such as "queue:my-queue". Use the LPOP command: Eject the element from the head of the queue and return its value, such as LPOP queue:my-queue. Processing empty queues: If the queue is empty, LPOP returns nil, and you can check whether the queue exists before reading the element.

How to start the server with redis How to start the server with redis Apr 10, 2025 pm 08:12 PM

The steps to start a Redis server include: Install Redis according to the operating system. Start the Redis service via redis-server (Linux/macOS) or redis-server.exe (Windows). Use the redis-cli ping (Linux/macOS) or redis-cli.exe ping (Windows) command to check the service status. Use a Redis client, such as redis-cli, Python, or Node.js, to access the server.
