[Java interview] what is idempotent? How to solve idempotency problem?
A fan who has worked in the traditional industry for 7 years sent me a private message. Recently, he went to many Internet companies for interviews and encountered many technologies and concepts that he had never heard of. One of the questions is: “what is idempotent and how to solve the problem of idempotence”? He […]

Detailed explanation of coroutine synergy principle in Android
preface Coroutine is a concurrent scheme. It is also a kind of thought. Traditionally, the coroutine is single threaded. In the face of IO intensive tasks, it consumes less memory and is more efficient. But in the face of computing intensive tasks, it is not as efficient as multi-threaded parallel computing. Different languages have different […]

Manage order status. Should I use the state machine? Lightweight state machine cola Statemachine nanny level tutorial
preface In the development of ordinary back-end projects, the use of state machine mode is not as common as you think. Because I didn’t work in the e-commerce field before, I rarely used state machine to manage various states in business code. Generally, I manually get/set state values. Last year, the author entered the e-commerce […]

Deeply understand the working mechanism behind ngrx effect
Blog address:https://indepth.dev/posts/120… an action is a constituent of a reducer, as well as of an effect. NgRx ensures that actions are first handled by the reducers, after which they will eventually be intercepted by the effects. Actions is an integral part of reducer and effect. Ngrx ensures that operations are first processed by the reducer, […]

Design pattern learning notes (XX) state pattern and its implementation
A state pattern allows an object to change its behavior when its internal state changes, and the object appears to have modified its class. It is generally used to realize the state machine, which is often used in the development of games, workflow engines and other systems: Finite state machine (FSM), which has three components: […]
