 Description   

Due to the ability to have checkpoints that are immutable with WiredTiger, MongoDB could create checkpoints at a given point in time.

A checkpoint would be created by each replica of a replica set at the same point in time.

It would allow to run operations or scripts to compare data, while the database instance is still accepting writes.

Durable History should allow reads at a specific point in time for cluster wide snapshot reads
