MongoDB is a clustered, BSON-native database (not JSON) that requires minimum three nodes for reliable primary elections, rewrote its storage engine since the 2.4 era and adds roughly one major release per year. It supports ACID snapshot isolation with multi-document transactions (including sharded clusters), offers an aggregation pipeline with $lookup for relationships, and provides Atlas for autoscaling, backups, full‑text search and serverless functions. Defaults now enforce authentication and single-document updates are atomic.
