According to an embodiment, an information processing system includes a client apparatus and three or more server apparatuses that each store data. The server apparatus includes a first storage, a receiver, a generator, a selector, a transmitter, and a changer. When the number of requests indicating identical changes among the requests of the data candidates is larger than a first threshold, the selector selects one of the requests indicating identical changes, and sets the state of the selected request to a second state. The transmitter transmits the data candidate including the selected request to one or more server apparatuses. When the number of requests in the second state among the requests of the data candidates is larger than a second threshold, the changer updates the history data and changes the data by using one of the data candidates including the requests in the second state. |

1. An information processing system comprising:
one or more client apparatuses; and N server apparatuses configured to store data, N being an integer larger than or equal to three, wherein each client apparatus includes
a transmitter configured to transmit a request indicating changes of the data to any one of the server apparatuses, and each server apparatus includes
a first storage configured to store the data and history data in which the request is linked to an order number that indicates an order in which the data is changed in accordance with the changes in the request,a receiver configured to receive the request from the client apparatus, and receive a data candidate, the data candidate including a current order number that indicates an unused order number among the order numbers, the request that is a candidate to be registered in the history data with the current order number, and a state of the request from one or more server apparatuses,a generator configured to set a state of the request received from the client apparatus to a first state, and generate a data candidate including the request in the first state, and the current order number,a selector configured to, when the number of requests indicating identical changes among the requests of the data candidates is larger than a first threshold, select one of the requests indicating the identical changes, and set a state of the selected request to a second state,a transmitter configured to transmit the data candidate including the selected request to one or more server apparatuses, anda changer configured to, when the number of requests in the second state among the requests of the data candidates is larger than a second threshold, update the history data and change the data by using one of the data candidates including the requests in the second state. |
