It is possible that a client c ships to the server log records of updates on a page p while not shipping the updated page p to the server. In other words, the server version of page p may not contain all updates that are found logged at the server. Explain why. What happens when some transaction running at another client wants to read or update page p? Is the transaction guaranteed to see the current version of page p? Also consider the case that client c crashes at that point.
