      A read-only transaction running at speculative majority or speculative snapshot will read its data from the most recent snapshot. It then will need to wait at commit time to ensure that the data it read is committed. We can do this by remembering the optime that the read transaction started with and then setting the last OpTime on the Client object to that optime in the commitTransaction command body.
