It appears that there is no documentation that I could find on read replication and how useMaster is not needed for select queries in a transaction for consistency. This PR should document the default behaviour of SELECT queries in a transaction when using read replication.
In V7 there will be a new setting for transactions to allow going to read pool only.
It could also be mentioned here maybe?
I also wonder (have not tested) what happens if one explicitly sets useMaster true/false inside a transaction.
Maybe something to document as well.
