Examples of com.thinkaurelius.titan.diskstorage.TemporaryStorageException

com.thinkaurelius.titan.diskstorage.TemporaryStorageException
This exception signifies a (potentially) temporary exception in a Titan storage backend, that is, an exception that is due to a temporary unavailability or other exception that is not permanent in nature.
If this exception is thrown it indicates that retrying the same operation might potentially lead to success (but not necessarily)
