Interface DropFlowFileStatus

public interface DropFlowFileStatus
Represents the status of a Drop FlowFile Request that has been issued to a FlowFileQueue. When a queue is requested to drop its FlowFiles, that process may be rather lengthy in the case of a poorly behaving FlowFileRepository or if the destination Processor is polling from the queue using a filter that is misbehaving. As a result, the dropping of FlowFiles is performed asynchronously. This status object provides information about how far along in the process we currently are and information about the success or failure of the operation.
