implement-reactive-r2dbc

What problem does it solve?

Defines the recommended approach for building reactive data access layers with R2DBC in Firefly Framework services, including entity definitions, repositories, migrations, connection pooling, and naming conventions.

Core Features & Use Cases

• Reactive data modeling: Define R2DBC entities using non-JPA annotations and validate mappings with Spring Data Relational.
• Reactive repositories and templates: Use ReactiveCrudRepository, R2dbcEntityTemplate, and DatabaseClient for non-blocking data access and complex queries.
• Migrations and auditing: Create Flyway migrations and enable R2dbc auditing for created/updated timestamps.
• End-to-end workflow: From entity to repository to migrations to configuration, including mapping DTOs with MapStruct.
• Use Case: Build a small service where an Account entity is persisted reactively with auditing and migrations.

Quick Start

Create a minimal Reactive R2DBC module by defining an entity, a reactive repository, and a Flyway migration to bootstrap the data layer.
