International Classification:

G06F 16/27
G06F 16/23

Abstract:

A computer-implemented method for performing data synchronization between a plurality of computing devices within a communication network includes detecting, by a first computing device of the plurality of computing devices, a changed data field of a plurality of available data fields within a first database table tuple. A bitmap within a plurality of configuration fields of the first database table tuple is updated to indicate a bit location associated with the changed data field. Synchronization data including the changed one or more data fields, the bitmap, and a version number of the first database table tuple within the plurality of configuration fields is sent to a second computing device. A conflict resolution procedure is performed based on a synchronization response received from the second computing device. The synchronization response includes status information associated with the synchronization of the changed data field

- Plano TX, US
Kamini Jagtiani - Los Altos CA, US

Assignee:

Futurewei Technologies, Inc. - Plano TX

International Classification:

G06F 17/30

Abstract:

A device such as a data storage system comprises a non-transitory memory storage comprising instructions, and one or more processors in communication with the memory. The one or more processors execute the instructions to: map a different portion of data in a storage device to each of different caches, wherein each cache is in a computing node with a processor; change a number of the computing nodes; provide a modified mapping in response to the change; and pass queries to the computing nodes. The computing nodes can continue to operate uninterrupted while the number of computing nodes is changed. Data transfer between the nodes can also be avoided.

Appl. No.:

14/601679

Inventors:

- Plano TX, US
Qingqing Zhou - Santa Clara CA, US
Kamini Jagtiani - Sunnyvale CA, US

International Classification:

G06F 17/30

Abstract:

In one embodiment, a method includes determining a number of initial servers in a massively parallel processing (MPP) database cluster and determining an initial bucket configuration of the MPP database cluster, where the initial bucket configuration has a number of initial buckets. The method also includes adding a number of additional servers to the MPP database cluster to produce a number of updated servers, where the updated servers include the initial servers and the additional servers and creating an updated bucket configuration in accordance with the number of initial servers, the initial bucket configuration, and the number of additional servers, where the updated bucket configuration has a number of updated buckets. Additionally, the method includes redistributing data of the MPP cluster in accordance with the updated bucket configuration.

International Classification:

G06F 15/173

US Classification:

709223

Abstract:

An embodiment method for massively parallel processing includes initiating a management instance on an initial machine, the management instance generating an initial partition corresponding to the initial machine, determining a total number of partitions desired for processing a database, the total number of partitions including the initial partition, determining a number of additional machines available to process the database, grouping the initial machine and the additional machines together in a pod, and launching the management instance on the additional machines in the pod to generate the total number of partitions desired for the database. Additional embodiment methods and an embodiment system operable to perform such methods are also disclosed.
