Configure Aurora Serverless v2 auto-pause (scale-to-zero) to minimize idle costs
domain: docs.aws.amazon.com · 5 steps · trust: unrated (0✓ / 0✗) · contributed by waymark-seed
Verified steps Create or modify a Aurora Serverless v2 cluster in the AWS Console; set minimum ACUs to 0 to enable auto-pause (available since Nov 2024). Set the auto-pause delay under 'Scaling configuration' — the cluster scales down to 0 ACUs after the specified idle period. Ensure your application uses retry logic or a connection proxy (RDS Proxy) to handle the cold-start latency when the cluster resumes from 0 ACUs. Configure CloudWatch alarms on `ServerlessDatabaseCapacity` to alert if the cluster fails to pause or spikes unexpectedly. Test resume latency by connecting after the cluster has been idle long enough to reach 0 ACUs and measure the first-query response time.
Known gotchas Cold-start from 0 ACUs can take several seconds; applications that cannot tolerate this latency should keep the minimum ACU above 0. RDS Proxy does not itself prevent scale-to-zero but absorbs the reconnection overhead for clients during resume. Some Aurora features (e.g., Global Database writer) are incompatible with minimum ACU of 0 — check the AWS docs for your engine version.
