Abstract
Embodiments of the present disclosure relate to a method, system, and computer program product for data management. According to the method, one or more processors divide data into a plurality of partitions. The one or more processors store the plurality of partitions in a plurality of nodes of a mixed distributed database system, wherein a first node of the mixed distributed database system comprises a plurality of databases, and wherein at least a part of the plurality of partitions are shared by the plurality of databases of the first node and being not shared by other of the plurality of nodes.
Claims20
A computer-implemented method comprising:
- dividing, by one or more processors, data into a plurality of partitions;
- and
- storing, by the one or more processors, the plurality of partitions in a plurality of nodes of a mixed distributed database system;
- wherein a first node of the mixed distributed database system comprises a first plurality of databases;
- and
- wherein at least a part of the plurality of partitions are shared by the plurality of databases of the first node and being not shared by other of the plurality of nodes.
A system comprising:
- a processing unit;
- and
- a memory coupled to the processing unit and storing instructions thereon, the instructions, when executed by the processing unit, performing acts comprising:
- dividing data into a plurality of partitions;
- and
- storing, by the one or more processors, the plurality of partitions in a plurality of nodes of a mixed distributed database system;
- wherein a first node of the mixed distributed database system comprises a plurality of databases;
- and
- wherein at least a part of the plurality of partitions are shared by the plurality of databases of the first node and being not shared by other of the plurality of nodes.
A computer program product being tangibly stored on a non-transient machine-readable medium and comprising machine-executable instructions, the instructions, when executed on a device, causing the device to perform acts comprising:
- dividing data into a plurality of partitions;
- and
- storing, by the one or more processors, the plurality of partitions in a plurality of nodes of a mixed distributed database system;
- wherein a first node of the mixed distributed database system comprises a plurality of databases;
- and
- wherein at least a part of the plurality of partitions are shared by the plurality of databases of the first node and being not shared by other of the plurality of nodes.
