MongoDB: Advantages of an Open Source NoSQL Database
summary
MongoDB is an open source document database (BSON, written in C++) that favors flexible schemas and in-memory performance for web‑scale apps; production best practice is a three‑node replica set (demo boots three mongod instances on 27017/27018/27019 and initates election), horizontal scale uses sharding where each shard is a replica set, and the 12‑byte ObjectId is autogenerated. Ops advice: run 64‑bit, prioritize RAM and SSDs to keep the working set in memory, use LVM snapshots or mongodump for backups, and enable monitoring.
