MongoDB 3.2 is now generally available, offering numerous features and enhancements that extend its capabilities to support diverse use cases. The new pluggable storage engines, including WiredTiger, MMAPv1, Encrypted, and In-Memory, provide flexibility for users to mix and match storage engines within a single MongoDB cluster, allowing them to meet specific application needs without the need for complex custom integration code. With WiredTiger as the default storage engine, MongoDB 3.2 offers improved performance by 7-10x and reduced storage overhead of up to 80%. The new Encrypted storage engine provides protection of data at-rest with advanced authentication, authorization, auditing, and network encryption security controls, while minimizing performance overhead to around 15%. Additionally, the In-Memory storage engine enables flexible in-memory computing for demanding applications.
