Abstract
A method for implementing distributed database management system operations on a computer cluster. The method includes defining ownership relationships between a plurality of computers in the computer cluster and a plurality of data nodes in the computer cluster, wherein a distributed database management system operation can be directly carried out by a first computer only on those data nodes owned by the first computer. The method further includes monitoring database usage characteristics. The method further includes carrying out a re-architecture step in response to the database usage characteristics by redefining ownership relationships to improve the efficiency of the distributed database management system operations.
Claims20
A method for implementing distributed database management system operations on a computer cluster, the method comprising:
- defining ownership relationships between a plurality of computers in the computer cluster and a plurality of data nodes in the computer cluster, wherein a distributed database management system operation can be directly carried out by a first computer only on those data nodes owned by the first computer;
- monitoring database usage characteristics;
- and
- carrying out a re-architecture step in response to the database usage characteristics by redefining ownership relationships to improve the efficiency of the distributed database management system operations.
A computer-readable storage medium including program instructions for implementing distributed database management system operations on a computer cluster, the program instructions which when executed by a computer system cause the computer system to execute a method comprising:
- defining ownership relationships between the plurality of computers in the computer cluster and a plurality of data nodes in the computer cluster, wherein a distributed database management system operation can be directly carried out by a first computer of the plurality of computers only on those data nodes owned by the first computer;
- monitoring database usage characteristics;
- and
- carrying out a re-architecture step in response to the database usage characteristics by redefining ownership relationships to improve the efficiency of the distributed database management system operations.
A computer-program product, for use in a computer, for implementing distributed database management system operations on a computer cluster including a processor and a memory, the computer program product comprising a computer-usable storage medium tangibly embodying computer readable program code, the computer program product comprising:
- code for defining ownership relationships between a plurality of computers in the computer cluster and a plurality of data nodes in the computer cluster, wherein a distributed database management system operation can be directly carried out by a first computer only on those data nodes owned by the first computer;
- code for monitoring database usage characteristics;
- and
- code for carrying out a re-architecture step in response to the database usage characteristics by redefining ownership relationships to improve the efficiency of the distributed database management system operations.
