These optimizations significantly reduce memory usage and query times, allowing applications to handle higher volumes of data more efficiently.

Advanced Security Features

Security remains a top priority in MongoDB 8.0, with the expansion of Queryable Encryption. This industry-first innovation allows customers to:

• Encrypt sensitive application data
• Store it as fully randomized encrypted data in the database
• Run expressive queries on the encrypted data without requiring cryptography expertise 2
