Abstract
Common data are maintained by a system including a plurality of node devices that each store a respective portion of a common data in a respective database, wherein a node device of the plurality of node devices stores a first portion of the common data, and receives a hash value of a second portion of the common data that is different from the first portion, in response to an update of the second portion of the common data.
Claims14
A system comprising:
- a plurality of node devices that each store at least a respective portion of a common data in a respective database, wherein at least one node device from the plurality of node devices is configured to:
- store a first portion of the common data;
- and
- receive a hash value of a second portion of the common data that is different from the first portion, in response to an update of the second portion of the common data.
A device comprising:
- a storing section configured to store a first portion of a common data;
- and
- a receiving section configured to receive a hash value of a second portion of the common data that is different from the first portion, in response to an update of the second portion of the common data.
-19. (canceled)
A computer program product having instructions embodied therewith, the instructions executable by a processor or programmable circuitry to cause the processor or programmable circuitry to perform operations of a method, the method comprising:
- storing a first portion of a common data in at least one node device from a plurality of node devices;
- and
- receiving a hash value of a second portion of the common data that is different from the first portion, in response to an update of the second portion of the common data by the at least one node device, wherein each of the plurality of node devices stores at least a respective portion of the common data in a respective database.
