  • Patent number: 9128776
    Abstract: A stop unit stops transmitting data to a plurality of nodes for every predetermined period. An acquisition unit acquires versions of routing tables, which are updated in accordance with movement of a query, from the plurality of nodes when the transmission of the data is stopped. A comparison unit compares the versions of the routing tables of the plurality of nodes that are acquired. When there is a node in which the routing table of an old version is stored as a result of the comparison, an update unit updates the routing table of the node.

  • Patent number: 8429136
    Abstract: A first node apparatus included in a distributed data store acquires first operation information and a first timestamp corresponding to target data. The first operation information specifies a first operation to be executed on the target data. The first timestamp indicates a first receipt time of the first operation information. The first node apparatus determines whether the first receipt time is earlier than some of second receipt times on the basis of second timestamps and the acquired first timestamp. The second timestamp indicates the second receipt time of second operation information. The second operation information specifies a second operation executed on the target data. The first node apparatus re-executes the second operations together with the first operation on the target data in the order of the receipt time when it is determined that the first receipt time is earlier than some of the second receipt times.
