Shared Database Per Service Design Pattern Tutorial for Microservices with Examples

In this video we will learn about Shared Shared Database per Service design pattern for microservices. This is the 2nd design principle in Database design patterns category for microservices. Shared Database per Service offers data privacy, data resiliency and loose coupling in your application. In the shared-database-per-service pattern, the same database is shared by several microservices. Each service is free to use, access data from shared datastore. Database will maintain ACIDITY and ATOMICITY. In shared Database per Service pattern, each service should use transaction management of underlying database so the ACID property of the database can be utilized. Microservices often need to communicate with each other via shared database. You need to carefully assess the application architecture before adopting this pattern, and make sure that you avoid hot tables i.e., single tables that are shared among multiple microservices. All database changes must also be backward-compatible; for example, developers can drop columns or tables only if objects are not referenced by the current and previous versions of all microservices. ** Usage of this Design Pattern ** 1. Use this pattern when you don't want too much refactoring of your existing code base. 2. Use this pattern when you enforce data consistency by using transactions that provide atomicity, consistency, isolation, and durability (ACID). 3. Use this pattern when you want to maintain and operate only one database. 4. Use this pattern when you don’t want to completely redesign your existing data layer. 5. Use this pattern when you want each service is free to use data accessible to other services. ** Advantages of this Design Pattern ** 1. The primary benefit of the shared database is no need to span the transactions across the services. 2. Using shared database reduce redundancy in data storage. 3. Data synch between microservices is not required. 4. No possibility or very less possibility of inconsistent data. 5. Shared database allows writing complex queries with joins. ** Chapter Timestamps ** 0:00 Welcome to Shared Database per Service design pattern 1:08 Agenda of tutorial 2:28 Introduction of Shared Database per Service design pattern 3:49 Real world examples of Shared Database per Service design pattern 5:38 Usage of Shared Database per Service design pattern 6:37 Advantages of Shared Database per Service design pattern 8:02 Summary of Shared Database per Service design pattern 8:50 Next video on CQRS design pattern for microservices #microservices #shareddatabaseperservice #designpatterns ** CHECK OUT OUR OTHER VIDEOS ** Database per Service Design Pattern    • Database per Serv...   Difference between Monolithic and Microservice Architecture    • Difference betwee...   Spring boot project setup:    • Spring boot Proje...   Spring Boot Microservice with postgres database Project:    • Spring Boot Micro...   Prepare Docker file, Container and Build Image:    • Docker Tutorial f...   Deploy Docker Image AWS Elastic Container Service:    • Deploy Springboot...   Solid Principle Tutorial    • Solid Principles ...   ** CHECK OUR PLAYLISTS ** Microservice Architecture and Microservice Design Patterns Tutorial    • Microservice Arch...   Spring Boot Complete Tutorial    • Spring Boot Tutor...   Docker Containers Complete Tutorial    • Cloud & Container...   Solid Principles Tutorial    • Solid Principles ...   Java Design Pattern Complete Tutorial with Examples    • Java Design Patte...   ** ABOUT OUR CHANNEL ** CodeOneDigest is a youtube channel that produces videos on programming languages, cloud and container technologies, Software design principles, Java frameworks in English and Hindi languages.
