摘要： Provided is a failure recovery method for switching to a standby system if a failure occurs in an active system, which allows reduction of loads on the standby system and a network. A computer system, which receives data to which timestamp information is appended in a chronological order and processes the received data by registered queries, includes the active system for processing the received data and the standby system for processing the received data instead of the active system upon occurrence of a failure. The active system processes the received data by the respective queries according to a predefined sequence, and transmits results obtained from the received data by the respective queries to the standby system as intermediate data on a query basis at a predetermined timing. The standby system restores the data by processing the received data and the intermediate data if a failure occurs in the active system.

摘要： A computer for the stream data processing system includes a query recovery point management table. A recovery point management section determines a recovery point for the stream data processing system by identifying an oldest one of input tuples used for generating output tuples, which are managed, or an earlier tuple through the use of a query recovery point stored in the query recovery point management table, and transmits the determined recovery point for the stream data processing system to an additional computer. The additional computer stores the last-received recovery point for the stream data processing system in a checkpoint file. When the computer for the stream data processing system recovers from a fault, the additional computer transmits the data succeeding the stored recovery point to the computer for the stream data processing system.

摘要： A method and device for guaranteeing performance of stream data processing wherein a latency guarantee and a processing accuracy guarantee are possible while ensuring a real-time property. An execution system determination unit evaluates an amount of data currently present in a queue of an input data reception unit, calculation time, and the processing accuracy. Then, during a query process, if the amount of data in the queue increases for some reason, and is likely to be larger than the requested latency, the execution system determination unit changes the system to a calculation system by which the latency can be reduced within a range that a final quality can be allowed, on the basis of the evaluation result. Under the condition that the accuracy is reduced, if the latency is likely to be greatly lower than the requested latency, the system changes to a calculation system having a higher processing accuracy.
