Description
The following two pages (both 4.0 and 4.2 versions) state that secondary reads are blocked while oplog batches are being applied:
- https://docs.mongodb.com/manual/core/replica-set-sync/#replication
- https://docs.mongodb.com/v4.0/faq/concurrency/#how-does-concurrency-affect-secondaries
My understanding is that behaviour changed in MongoDB 4.0.
Can someone please confirm and update those pages if they are no longer correct?
