MongoDB 9.0

MongoDB 9.0 strengthens the foundation for modern applications and evolving AI workloads with improvements across performance, scalability, resilience, observability, security, and developer productivity. It helps teams support more users, transactions, and AI-driven activity before adding infrastructure or rearchitecting applications.

MongoDB 9.0 can be deployed via MongoDB Atlas, self-managed, locally and in various public or private cloud environments.

MongoDB 9.0 delivers significant performance and scalability improvements compared with previous versions, particularly for high-throughput and read-intensive workloads.

9.0 vs 8.0 using internal testing with public benchmarks:

Start by reviewing the MongoDB 9.0 upgrade documentation and compatibility changes. Back up your data, test the upgrade in a staging environment, confirm support for your operating system and drivers, and then follow the procedure for your deployment. MongoDB Atlas or self-managed (Enterprise Advanced and Community Edition) each have specific upgrade guidance.

As with any major version upgrade, review compatibility changes, deprecations, supported platforms, and driver requirements before you begin. Test your applications against the upgraded deployment, validate your backup and recovery plan, and schedule the change according to your organization’s operational requirements. The exact process and downtime profile depend on your deployment type and topology.

Yes. Each MongoDB major version has its own published lifecycle schedule. Starting with MongoDB 8.0, major versions follow a standard five-year lifecycle. Check the MongoDB Software Lifecycle Schedule for the exact end-of-life date for your current version and plan your upgrade before that date.

MongoDB 9.0 builds on MongoDB 8.0 with higher throughput, faster core operations, improved scaling efficiency, Intelligent Workload Management, expanded Queryable Encryption with prefix, suffix, and substring queries, new schema constraints, enhanced Atlas private networking, and unified observability through the Metrics UI, OpenTelemetry, and Query Stats.
