## Context

MongoDB 8.0 is the latest release of the MongoDB database, announced by a MongoDB executive reflecting on their first year at the company. The post details the development process, performance benchmarks, and key features of the release, along with customer testimonials and availability information.

## Approach / What changed

The MongoDB team set a goal to make MongoDB 8.0 the best-performing version yet, focusing on security, durability, availability, and performance. They ran a suite of benchmarks to simulate customer workloads, developed automation to automatically roll back code that regressed performance, and held regular reviews with senior engineering leaders. The team also ‘dogfooded’ the release by moving their own applications to MongoDB 8.0, which resulted in a 75% drop in query latencies for their internal build system.

## Takeaways

- MongoDB 8.0 delivers significant performance gains, including 36% better read throughput, 56% faster bulk writes, and 200% faster complex aggregations of time series data, with typical web applications performing 32% better overall.
- The release includes sharding enhancements that distribute data across shards up to 50 times faster and at up to 50% lower starting cost, reducing the need for additional configuration.
- MongoDB 8.0 introduces quantized vectors, which are compressed representations of full-fidelity vectors that require up to 96% less memory and are faster to retrieve while preserving accuracy, supporting search and AI applications at higher scale and lower cost.

## FAQ

### How much faster is MongoDB 8.0 compared to previous versions?

MongoDB 8.0 shows significant performance improvements: 36% better read throughput, 56% faster bulk writes, 20% faster concurrent writes during data replication, and 200% faster complex aggregations of time series data. MongoDB's internal build system saw query latencies drop by approximately 75% after upgrading.

### What are the key new features in MongoDB 8.0?

Key features include sharding enhancements for up to 50 times faster data distribution, quantized vectors that reduce memory usage by up to 96%, and expanded Queryable Encryption to support range queries, allowing encryption of data at rest, in transit, and in use.

### How can I get MongoDB 8.0?

MongoDB 8.0 is available today via MongoDB Atlas, as part of MongoDB Enterprise Advanced for on-premises and hybrid deployments, and as a free download from mongodb.com/try with MongoDB Community Edition. Upgrade guides are available for customers upgrading from previous versions.
