Detailed explanation of asynchronous task processing in Redis

As web applications continue to evolve, the need for asynchronous task processing becomes increasingly important, as we need to ensure that users can continue using the application until the task is completed. In this case, except for asynchronous task processing, multi-task parallel processing cannot be achieved, so it is often necessary to use some tools to handle asynchronous tasks, of which Redis is a very useful tool. Redis is a high-performance in-memory database that can be used to quickly store, read and manipulate data. Its primary use is to implement caching and messaging, however, it can also

Analysis of application scenarios of Redis in artificial intelligence

With the continuous development of artificial intelligence technology, more and more companies are beginning to apply it in business scenarios, and the most critical part is data storage and processing. As a fast and efficient in-memory database, Redis has become the preferred solution for more and more artificial intelligence applications. One of the advantages of Redis is its fast read and write performance. Because Redis data is stored in memory, its read and write speeds are much faster than traditional hard disk storage. This means that when we need to process large amounts of real-time data, Red

Comparison of distributed self-increasing ID solutions implemented by Redis

In distributed application development, the generation of auto-incrementing IDs is a common requirement. In a stand-alone environment, you can use the database's auto-increment primary key to implement auto-increment ID. However, in a distributed environment, using auto-increment primary keys will cause duplication. Therefore, other solutions need to be used to ensure the uniqueness of auto-increment IDs. Redis is a high-performance in-memory database that can implement distributed self-increasing ID solutions. In this article, we will introduce three common Redis distributed self-increasing ID solutions and compare them to help developers choose the appropriate one.

Detailed explanation of distributed transactions implemented by Redis

With the continuous growth of Internet transactions, distributed transactions have become an essential part of business systems. With the continuous enrichment of distributed transaction implementation methods, Redis, as a widely used in-memory database, is gradually becoming the first choice for distributed transaction implementation. This article mainly introduces how Redis implements distributed transactions. Redis transaction model The transaction model supported by Redis is batch operation. Within a transaction, Redis can execute multiple commands. Multiple commands all succeed or fail in the same transaction, ensuring that the transaction

How to use Redis's RDB and AOF methods

Redis persistence solution Redis is an in-memory database, and data is stored in memory. In order to avoid permanent loss of data due to process exit, the data in Redis needs to be regularly saved from memory to the hard disk in some form (data or commands). When Redis restarts next time, use the persistent file to achieve data recovery. In addition, persistent files can be copied to a remote location for disaster backup purposes. Redis provides multiple different levels of persistence: one is RDB and the other is AOF. RDB persistence can generate a point-in-time snapshot of the data set within a specified time interval, and save the database snapshot to

How to check Redis benchmark parameters

Redis comes with a tool called redis-benchmark to simulate N clients issuing M requests at the same time. (similar to the Apacheab program). You can use redis-benchmark-h to view benchmark parameters. The following parameters are supported: Usage:redis-benchmark[-h][-p][-c][-n[-k]-hServerhostname(default127.0.0.1)-pServerport(default6379)-sServersocket(overrideshostandport)-cNumberofparal

What is the event-driven model of Redis?

Why doesn't Redis use the basic Socket programming model? When using the Socket model to implement network communication, you need to go through multiple steps such as creating a Socket, listening to ports, processing connections, and reading and writing requests. Now we will take a closer look at the key operations in these steps to help us analyze the Socket model. insufficient. First, when we need to communicate between the server and the client, we can create a listening socket (ListeningSocket) that listens to client connections on the server through the following three steps: call the socket function to create a socket. We usually call this socket an active socket (ActiveSocket); call the bind function,

How to implement concurrent queuing based on redis optimistic locking

There is a demand scenario where redis is used to control the number of scrapy runs. When the system background is set to 4, scapry is only allowed to start 4 tasks, and excess tasks are queued. Overview I recently built a django+scrapy+celery+redis crawler system. In addition to running other programs, the host purchased by the customer also needs to run the program I developed, so it is necessary to manually control the number of scrapy instances to avoid too many crawlers. Put a burden on the system. Process design 1. The crawler task is initiated by the user in the form of a request, and all user requests are uniformly entered into celery for queuing; 2. The execution of task number control is handed over to reids and saved through celery

How SpringBoot uses RedisTemplate to operate Redis data types

Spring encapsulates RedisTemplate to operate Redis, which supports all Redis native APIs. Operation methods for five data structures are defined in RedisTemplate. opsForValue(): operates on strings. opsForList(): Operation list. opsForHash(): operates hash. opsForSet(): Operation set. opsForZSet(): operates an ordered set. Below are examples to understand and apply these methods. What needs special attention here is that the data must be cleared after running the above method, otherwise running it multiple times will result in repeated data operations. (1) Use Maven to add dependency files

How to use Redis's expiration strategy and memory elimination strategy

1. Set keyexpirekeyseconds with expiration time. Time complexity: O(1) Set the expiration time of key. After timeout, the key will be automatically deleted. In Redis terminology the timeout associated with a key is volatile. After timeout, it will only be cleared when DEL, SET, or GETSET is executed on the key. This means that conceptually all operations that change the key without replacing it with a new value will keep the timeout unchanged. For example, using INCR to increment the value of a key, executing LPUSH to push a new value into a list, or using HSET to change a hash field will keep the timeout unchanged. Use the PERSIST command to clear the timeout so that it

How to solve Redis related problems

Redis persistence mechanism Redis is an in-memory database that supports persistence. It synchronizes data in memory to hard disk files through the persistence mechanism to ensure data persistence. When Redis is restarted, the data can be restored by reloading the hard disk files into the memory. Implementation: Create a fork() child process separately, copy the database data of the current parent process to the memory of the child process, and then write it to a temporary file by the child process. After the persistence process is over, replace it with this temporary file. snapshot file, then the child process exits and the memory is released. RDB is the default persistence method of Redis. According to a certain time period strategy, the memory data is saved to a binary file on the hard disk in the form of a snapshot. That is Sn
