An Appian process instance stores data in memory, you do not have to persist to the DB and the data will be removed from your process reports when the process instance is archived or deleted. This may work for your use case?
Otherwise, how short of a time period? How much data? What do you intend to do with the data while it is 'stored temporarily'?
