# Amazon EMR Serverless now supports live configuration updates without application restarts

**[AWS](https://daily.dev/sources/aws)** · 1 min read · 0 upvotes · 0 comments

## Summary

Amazon EMR Serverless now allows updates to key application configurations — such as maximum capacity and custom image settings — without stopping and restarting the application. New workloads submitted after an update automatically use the new settings, while existing workloads continue uninterrupted. Previously, these changes required a full stop-and-restart cycle, forcing maintenance windows and blocking job submissions. The feature is available across all EMR releases and AWS Regions where EMR Serverless is supported.
