Docker Compose simplifies the management of multi-container applications by defining services, networks, and volumes in a single YAML file.
with a single command, we can create and start all the services from yaml file.
let’s see how we use docker compose in Spring Boot. Github Demo / Docker Compose Support in Spring Boot
Backoff is a strategy for dealing with failures, conflicts, or resource competition.
The core logic is: when an operation fails or encounters a limitation, it will pause for a period of time before trying again, and the retry interval is usually adjusted dynamically to avoid increasing system pressure or conflicts.
let’s see how spring-framework implement it.
in Spring-Framework 7.0, Spring team redesigned a minimal core retry feature in spring-core. inspired by the Spring Retry project.
currently only with 3 classes & 4 interfaces.
let’s deep into it.

when I try to read the spring-integration code, I find it is essential to know spring-messaging first. some concepts are same like message channel, pollable / subscribable channel, asynchronious, integration, etc.
spring-messaging is a sub-module under spring-framework. it highly abstracts the components when two systems needs to communicate via messages.
The more design patterns we talk about, the less powerful a language is.
The more powerful a language is, the more we will use integrated features than design patterns.
list few design patterns which are really excited to use with the evolution of Java.
