  • Patent number: 11271809
    Abstract: Upon receiving an input of data, an input unit transmits a time notification to another input unit and transmits a data notification including the input clock time to a storage unit. Upon receiving a time notification from another input unit, the input unit transmits an empty notification including the input clock time to the storage unit to indicate there is no input before the input clock time. Upon receiving the data notification from an input unit having received the input of data and receiving the notification from the other input unit, the storage unit broadcasts the data in order, assuming that consensus of the plurality of storage units is confirmed. When adding an input unit to a computer system, a control device causes the storage unit to start confirming the consensus including the joining input unit after a window interval has elapsed after the joining input unit starts operation.

  • Patent number: 11106552
    Abstract: A distributed processing method to receive data by a plurality of servers each including a processor and a memory, and process the data by replicating, the method includes a first determination step in which the servers each receive the replicated data, and a first determination unit determines a degree of consistency of the received data and an output step in which the servers each receive a determination result of the degree of consistency of the data from the first determination unit, and if the determination result includes data that guarantees consistency, the server outputs the data that guarantees consistency. A first number of servers that are to receive the data is set in advance based on a prescribed allowable number of failures that defines the number of servers that can have failures, and an allowable number of byzantine failures that defines the number of servers that can have byzantine failures.

  • Patent number: 10719496
    Abstract: This computer system includes a plurality of nodes for forming a distributed KVS. The plurality of nodes have a plurality of key ranges to which upper-limit data amounts are set, each upper-limit data amounts being an upper limit of an amount of manageable data. When a new key range is created, the plurality of nodes lowers an upper-limit data amount of an existing key range so that the sum of an upper-limit data amount of the new key range and an upper-limit data amount of the existing key range does not exceed a maximum amount which is the amount based on the volume of the memory of the computer apparatus.
