  • Publication number: 20240126747
    Abstract: A data store comprises a commit management map including an identifier of a distributed transaction. A control method executed by an adapter coupled to the data store includes: alternate processing of, temporarily storing the reception query, and causing a transaction on the data store side to execute the reception query; perpetuation processing of determining whether or not commit is possible using lock information and perpetuating the GXID to be committed and the temporarily stored reception query in a case where commit is possible; settlement processing of causing the transaction on the data store side to execute a GXID addition query that is a query that adds the GXID to be committed to the commit management map and committing the transaction on the data store side; and store restart processing of the adapter starting a new transaction at the data store for a distributed transaction in an in-doubt state.

  • 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.

    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.
