Introducing REST APIs in MySQL HeatWave 9.3.1: Unlocking Simplicity and Integration at Scale

Oracle continues to evolve its cloud-native data platform to empower developers and businesses with speed, flexibility, and automation. With the release of MySQL HeatWave version 9.3.1, Oracle now introduces REST API support — a major milestone that transforms the way users interact with HeatWave on Oracle Cloud Infrastructure (OCI).

This feature gives developers, DevOps teams, and data engineers a powerful new way to manage HeatWave clusters using secure, scalable, and standards-based HTTP APIs.

What Is MySQL HeatWave?

If you're new to the Oracle Cloud ecosystem, MySQL HeatWave is a fully managed database service that uniquely combines OLTP (transactional) and OLAP (analytical) capabilities — all within a single MySQL database engine.

It eliminates the need for ETL, reduces latency, and enables real-time analytics on live transactional data — and with version 9.3.1, it now becomes even more accessible through REST APIs.

What’s New in Version 9.3.1?

The 9.3.1 release of MySQL HeatWave includes support for a robust set of REST APIs that allow users to:

• Create and manage HeatWave clusters

• Monitor cluster status and health

• Scale clusters dynamically

• Access configuration and diagnostics

• Integrate HeatWave operations into CI/CD workflows

This means you can now build, control, and monitor your HeatWave environments programmatically, using any tool that can make HTTP requests — no SDKs, no CLI, no console dependencies.

Why REST APIs Matter

The introduction of REST APIs in version 9.3.1 represents a shift toward developer-first and automation-friendly database operations.

Seamless Integration

Use REST APIs to embed HeatWave operations into:

• CI/CD pipelines (e.g., GitHub Actions, Jenkins)

• Infrastructure-as-code frameworks (e.g., Terraform, Ansible)

• Custom admin dashboards or monitoring platforms

Automation-Ready

Automate repetitive tasks like:

• Auto-scaling clusters based on usage

• Scheduling start/stop operations to optimize costs

• Integrating alerts and logging into your observability stack

Secure by Design

REST APIs use IAM-based authentication and secure HTTPS communication, ensuring all operations are authorized and auditable — ideal for enterprise-scale workloads.

Real-World Use Cases

Data Engineering Teams: Automate pipeline triggers to scale up HeatWave before batch processing and scale down after.
AI/ML Workflows: Schedule analytics clusters for model training and shut down afterward.
Enterprise IT Ops: Integrate HeatWave controls into central dashboards or chatbot assistants.
DevOps Teams: Replace manual steps with API calls in deployment scripts or cloud orchestration templates.

Version & Availability

REST API support is available starting from MySQL HeatWave version 9.3.1, released in May 2025. All customers using OCI MySQL HeatWave in supported regions can now leverage these APIs to modernize and streamline their operations.

Final Thoughts

Oracle is pushing the boundaries of what a modern, intelligent data platform should offer. With the release of REST APIs in MySQL HeatWave 9.3.1, Oracle gives its users more control, more automation, and more integration possibilities — all in a fully managed and scalable cloud-native platform.
