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.
Claims20
A method to reduce the storage used in distributed databases, comprising:
- dividing common data into two or more portions according to one or more predetermined rules;
- storing a first portion of the common data in a database of at least one node device from a plurality of node devices, the first portion being a subset of the common data and being less than all of the common data;
- 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.
