Spring Data R2DBC with PostgreSQL Database on Amazon RDS

In this story, we’ll implement a sample REST API that uses Spring Data R2DBC with PostgreSQL Database on Amazon Relational Database Service.

Overview

The Reactive Relational Database Connectivity (R2DBC) project brings reactive programming APIs to relational databases. It defines a non-blocking SPI for database driver implementors and client library authors. R2DBC drivers fully implement the database wire protocol on top of a non-blocking I/O layer.

Creating an RDS PostgreSQL Instance

Amazon Relational Database Service (Amazon RDS) makes it easy to set up, operate, and scale a relational database in the cloud. It provides cost-efficient and resizable capacity while automating time-consuming administration tasks, such as hardware provisioning, database setup, patching, and backups. It frees you to focus on your applications so you can give them the fast performance, high availability, security, and compatibility they need. — https://aws.amazon.com/rds/
