Study Notes
Service Discovery in Microservices Architecture
- Primary concern when implementing service discovery is managing the dynamic nature of services, such as registration, discovery, and deregistration.
Annotations in Spring Boot
-
@Configurationannotation in Spring Boot is used to indicate that a class declares one or more@Beanmethods and may be processed by the Spring container to generate bean definitions and service requests for those beans at runtime.
Hibernate Annotations
-
@ManyToOneannotation in Hibernate is used to establish a many-to-one relationship between two entities, where one side owns the relationship and the other side is the inverse of the relationship.
Communication Patterns in Microservices
- The Request-Reply pattern is commonly used in microservices architecture to handle communication between services, allowing services to exchange messages and respond to each other.
Singleton Pattern in Real-Time Systems
- The primary benefit of using the Singleton pattern in a real-time system is that it ensures a single instance of a class is created, providing a global point of access to that instance, and controlling access to it.
