Patent Searching and Data


Title:
INFORMATION PROCESSING DEVICE, DATA PROCESSING METHOD, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2016/027455
Kind Code:
A1
Abstract:
The present invention efficiently performs distributed batch processing for an eventual consistency storage system. A control node (100) includes an execution control unit (110) and a re-execution control unit (140). The execution control unit (110) makes a processing node (200) execute prescribed processing that includes readout of key-associated data that are stored in a distributed data store (300). After the processing node (200) has been made to execute the prescribed processing, the re-execution control unit (140) determines, on the basis of a representative value for the data, whether it is possible that, at the time that the prescribed processing was executed, an inconsistency had been generated in the key-associated data stored in the distributed data store (300). When it is determined that it is possible that an inconsistency had been generated, once elimination of the inconsistency has been confirmed, the re-execution control unit (140) makes the processing node (200) re-execute the prescribed processing.
