title: "MongoDB 9.0: This Is What a Database Should Be"
description: "MongoDB 9.0 is the most advanced release in MongoDB’s history, designed to eliminate the tradeoffs that force organizations to add infrastructure, compromise security, or rethink architecture as applications grow. Transactional workloads achieve up to 20% higher throughput compared to 8.0, with find-one queries up to 35% faster and update-one queries up to 30% faster, and large deployments see nearly 2x higher throughput. Queryable Encryption now supports prefix, suffix, and substring queries, enabling partial-match searches on encrypted data throughout its lifecycle. Intelligent Workload Management queues transient traffic spikes during overload to keep clusters responsive, buying time for auto-scaling or operator intervention. The release also includes redesigned Atlas Metrics UI, enhanced OpenTelemetry integration for streaming metrics to platforms like Datadog and Prometheus, and a MongoDB extension for Hibernate ORM to ease modernization."

## FAQ

### What performance improvements does MongoDB 9.0 offer over 8.0?

MongoDB 9.0 achieves up to 20% higher throughput for transactional workloads, with find-one queries up to 35% faster and update-one queries up to 30% faster. Large deployments see nearly 2x higher throughput.

### How does Queryable Encryption work in MongoDB 9.0?

Queryable Encryption now supports prefix, suffix, and substring queries, enabling applications to perform partial-match searches on encrypted data throughout its lifecycle, without sacrificing security.

### What is Intelligent Workload Management?

Intelligent Workload Management is a managed availability capability that queues transient traffic spikes during overload, keeps short-running operations moving, and throttles excess requests only as a last resort to maintain cluster stability.
