(Maybe include a discussion of how MongoDB read concerns translate into particular read sources and data views.)
WiredTiger Snapshot
MongoDB Point-in-Time Reads
Definitely feel free to alter the layout and file additional tickets split the work into more manageable units. Please add topics if you can think of any. This outline is meant only to be a starting point.
