- Redis methods and application examples for implementing distributed task distribution
- Preface In distributed systems, task distribution is a very important part. Task distribution can ensure the balanced distribution of tasks on different nodes and avoid the risk of the entire system crashing due to excessive load on a node. In this article, we will introduce the distributed task distribution method of Redis and demonstrate it with application examples. The purpose of this article is to help readers better understand and apply the advantages of Redis in distributed systems. Redis's distributed task distribution method Redis is an efficient NoSQL database.

- How to store data in php
- With the continuous development of network technology, the storage and processing of Internet digital information has become a key business. In network application development, how to store and manage data is a big problem. Although the PHP language is a scripting language, it has strong data processing and storage capabilities. In this article, we will introduce the ways in which PHP stores data. 1. File storage File storage is the most basic storage method. In PHP, you can use fopen(), fwrite(), fread() and other functions to read and write files to achieve data storage.

- Java embedded data engine from SQLite to SPL instance analysis
- The data engines that can be embedded in Java applications seem to be rich, but in fact it is not easy to choose. Redis has poor computing power and is only suitable for simple query scenarios. The Spark architecture is complex and heavy, making deployment and maintenance very troublesome. Embedded databases such as H2\HSQLDB\Derby have simple structures, but their computing capabilities are insufficient and they do not even support basic window functions. In contrast, SQLite has achieved a good balance in architecture and computing power, and is a widely used Java embedded data engine. SQLite adapts to conventional basic application scenarios. SQLite has a simple structure. Although its core is developed in C language, it is well packaged and presented to the outside as a small Jar package, which can be easily integrated in Java.

- How Java architecture is applied to different products
- When we set up a system, we usually need to consider how to interact with other systems, so we first need to know how various systems interact with each other and what technology is used to implement it. 1. Interaction between different systems and different languages. Nowadays, our common interactions between different systems and different languages use WebService and Http requests. WebService, that is, "Web service", abbreviated as WS. Literally understood, it is actually a "Web-based service". But services are for both parties. If there is a service demander, there will be a service provider. The service provider publishes services to the outside world, and the service demander calls the services published by the service provider. To put it more professionally, WS is actually built on the HTTP protocol to achieve heterogeneity.
