module Mongo::ChangeStream


Change streams allow applications to access real-time data changes without the complexity and risk of tailing the oplog.

Applications can use change streams to subscribe to all data changes on a single collection, a database, or an entire deployment, and immediately react to them. Because change streams use the aggregation framework, applications can also filter for specific changes or transform the notifications at will.

NOTE for more details, please check the official manual.
