vue3 + springboot3 large file breakpoint resume upload
Preface: 1. Requirements: Files above 10MB support breakpoint resumption and require a real-time progress bar. 2. There are currently two ways to implement breakpoint resumption on the Internet. The main difference is whether the action of cutting files is on the front end or the back end. (This article implements cutting files on the front […]

Technical breakdown | Why does Redis use different encodings internally?
One weekend night, I suddenly received a wave of alarms about increased time consumption. After a closer look at the alarm message, it turned out that a slow check request occurred, which caused a significant increase in cluster time consumption. At this time, business students also received alarms that upstream services were affected. During the […]

Using Hystrix to implement circuit breakers in Spring Cloud
1. Why use Hystrix When calling between multiple microservices, assume that microservice A calls microservice B and microservice C, and microservice B and microservice C are calling other microservices. This is the so-called “fan-out”. If the call response time of a certain microservice on the fan-out link is too long or is unavailable, the call […]
