Class DeltaFileUploader

java.lang.Object

org.gcube.indexmanagement.storagehandling.DeltaFileUploader

public class DeltaFileUploader
extends Object

This class implements an uploader of delta files to the Content Management layer. Each time a new delta file is created as a result of new data added to (or removed from) the index, the file is added to the uploader queue in order to be stored in the CMS. After the file finally gets uploaded, a notification is sent to the index management resource, so that the delta file list is updated.
