Netty's threading model Reactor model Netty's model is based on Reactor mode, so we must know Reactor first. The Reactor model is also called the Dispatch model. When one or more requests are sent to the server at the same time, the server synchronously assigns them to the processing threads of each request. Three roles of Reactor model Ac ...

We will use a series to explain the complete practice of microservices from requirements to online, from code to k8s deployment, from logging to monitoring. The whole project uses the micro services developed by go zero, which basically includes go zero and some middleware developed by relevant go zero authors. The technology stack used is basi ...

2. Service invocation 2.1 LoadBalancer integrates RestTemplate to call other micro services 2.1.1 introduction 2.1.1.1 introduction to resttemplate RestTemplate is a network request framework in Spring Resources that accesses third-party RESTful API interfaces. The design principle of RestTemplate is similar to that of other spring template ...

Through the previous study, we have learned how the primary container of spring is initialized, but compared with the unfamiliar XmlBeanFactory, ApplicationContext is obviously more familiar to everyone. The spring advanced container ApplicationContext contains all the things in the primary container XmlBeanFactory. Based on the primary contain ...

01. Hystrix circuit breaker 1. General Problems faced by distributed systems Problems faced by distributed systems Applications in complex distributed architecture have dozens of dependencies, and each dependency will inevitably fail at some time. Service avalanche When calling between multiple microservices, suppose that microse ...

Draft, need post-processing 01. Micro service architecture What is micro service? Microservice architecture is an architecture model. It advocates dividing a single application into a group of small services, which coordinate and cooperate with each other to provide final value for users. Each service runs in its own independent process ...

Background analysis In microservices, the first problem we need to face is how to find services (software is a service), and the second is how to communicate between different services? How to manage every service in the application better and more conveniently, and how to establish the link between various services, so that the registration c ...

RPC in combination with Protobuf Here we use a demand scenario to learn relevant knowledge points: Suppose there is an Order module in a system. Other modules want to realize the remote project call of RPC. The Order information can be obtained according to the Order ID and timestamp. If the acquisition is successful, the correspondin ...
