Isolation and circuit breakers for service rooms-Hystrix
Service downgrade is when the server pressure increases sharply, some services and pages are strategically downgraded based on the current business conditions and traffic, so as to release server resources to ensure corenormal operation of the task.Hystrix is mainly to solve the service avalanche problem: Downgrade mechanism: When one of your services times out, lacks […]
Springcloud3 hystrix implementation of service degradation case configuration 2
A description of service downgrade 1.1 Service Downgrade Instructions “The server is busy, please try again later” does not let the customer wait, and immediately returns a friendly prompt. 1.2 Triggers of service downgrade 1. The program runs abnormally; 2. Timeout; 3. Service fusing triggers service downgrade; 4. When the thread pool/semaphore is full, it […]

Hystrix service circuit breaker
Getting started with SpringCloud – Hystrix service fusing 1. Hystrix service blown The fuse mechanism is a microservice link protection mechanism to deal with the avalanche effect. When a microservice on the fan-out link becomes unavailable due to an error or the response time is too long, the service will be degraded, thereby interrupting the […]
springcloud3 hystrix implements service degradation, circuit breaker, current limiting and case configuration 1
The role of hystrix 1.1 Downgrade, circuit breaker, current limiting 1. Service downgrade: If there is a problem with plan A, switch to cover-up plan B; 2. Service circuit breaker: triggering rules, power outage and gate restrictions, and service degradation 3. Service current limit: limit the number of requests. Two case configuration 2.1 Flowchart 2.2 […]
[Hystrix Technical Guide] (7) Analysis of the operation process principle of failover (including source code)
Background introduction At present, for some non-core operations, such as saving operation logs after increasing or decreasing inventory and sending asynchronous messages (specific business processes), once an MQ service exception occurs, the interface response will timeout, so you can consider introducing services for non-core operations Downgrade, service isolation. Hystrix Description official document Hystrix is an […]
[Hystrix Technical Guide] (1) Basic usage and configuration instructions
Many things in this world exist because of belief, so people make clay Buddha with their own hands, but choose to believe in it firmly. The scale and complexity of distributed systems continue to increase, and with it comes higher and higher requirements for the availability of distributed systems. In various high-availability design patterns, [fuse, […]
