Abstract:
PURPOSE: A method for processing a file of a storage system and data server according to the method can transmit the processed file. CONSTITUTION: A network interface unit (401) receives a file request from a client. A storage unit (403) stores a data file. An additional function processor (402) loads a file corresponding to the request from the storage unit. The additional function processor generates a result file by performing a process requested by the client for the loaded file. A control unit (404) transmits the result file generated to the client through the network interface. [Reference numerals] (401) Network interface unit; (402) Additional function processor; (403) Storage unit; (404) Control unit
Abstract:
PURPOSE: An apparatus and a method for processing a continuous process task in a distributed data stream processing system are provided to decentralize load concentrated on a specific task by allocating a continuous process task to nodes. CONSTITUTION: A control node(100) determines necessity about parallel process of a consecutive processing task about input data stream. The control node allocates the consecutive processing task for processing data stream division to distributed processing nodes(200). The distributed processing nodes process the consecutive processing task and integrate a processing result.
Abstract:
PURPOSE: A method and an apparatus for providing services are provided to support distributed continuous processing services with respect to large capacity stream data and storage data with various application environment and various formats. CONSTITUTION: A new service is registered in a data processing system(501). The system selects at least one node and/or at least one task executor according to the node. The node allocates tasks forming the new service. The system allocates the tasks to the task executor of the selected node and/or the selected task executor(503). The system dynamically executes scheduling processes based on the execution state of the tasks(504).
