Build a Spring Boot REST API with Amazon Aurora DSQL
Database Blog
This article demonstrates how to build a Spring Boot REST API integrated with Amazon Aurora DSQL, including IAM authentication, optimistic concurrency control, and multi-Region active-active deployment.
- Configure Aurora DSQL JDBC Connector for IAM authentication, token refresh, and TLS encryption
- Implement optimistic concurrency control with retry logic to handle 40001 SQL state errors
- Build a RESTful product inventory API with standard CRUD operations using Spring Boot 3.3
- Deploy application nodes across multiple AWS Regions with Application Load Balancer for traffic distribution
- Test concurrent multi-Region writes to verify active-active replication and data consistency
- Use HikariCP connection pooling with DsqlExceptionOverride to prevent connection eviction on conflicts
Aurora DSQL combined with Spring Boot enables scalable, globally distributed applications without traditional database operational overhead, with built-in multi-Region high availability and serverless architecture.
