(Query, index)License: AGPL (Drivers: Apache)Protocol: Custom, binary (BSON)Master/slave replication (auto failover with replica sets)Sharding built-in
Queries are javascript expressions
Run arbitrary javascript functions server-side
Better update-in-place than CouchDB
Uses memory mapped files for data storage
Performance over features
Journaling (with –journal) is best turned on
