There was a problem hiding this comment.
Previously, TimeoutContext was mutable, and we would set minRoundTripTime on it once a connection source (i.e., server) was selected. Now, this logic has been moved into SyncOperationHelper:
- In withReadConnectionSource
- And in withSuppliedResource
The reasoning is that once a server is selected, we know the round-trip time and can propagate a modified OperationContext to getConnection. This method either retrieves a connection from the pool or establishes a new one, and then passes it to the operation’s callback.
Note: minRoundTripTime is used when calculating the maxTimeMS value appended to a command in CommandMessage.
The same change has been applied to the async counterpart in AsyncOperationHelper.
