save row and key caches

Throws:

java.util.concurrent.ExecutionException - when attempting to retrieve the result of a task that aborted by throwing an exception

java.lang.InterruptedException - when a thread is waiting, sleeping, or otherwise occupied, and the thread is interrupted, either before or during the activity.
