MongoDB, a popular document-based database program, recently released version 8.0 with significant improvements in security, durability, availability, and performance. The new release includes architectural optimizations that have reduced memory usage and query times, as well as enhanced support for search and AI applications at higher scale and lower cost. Additionally, MongoDB's Queryable Encryption has been expanded to support range queries, allowing customers to encrypt sensitive application data while running expressive queries on the encrypted data without requiring cryptography expertise. The performance improvements in version 8.0 have led to reduced costs for users due to an improved price/performance ratio.
