Abstract

The invention discloses a data distribution and parallel processing method and system. The method comprises following steps: analyzing an initial query instruction to obtain an actual query instruction; distributing the actual query instruction to different data nodes through working distribution nodes; executing the received actual query instruction on each data node and returning query results to the work distribution nodes; at the same time, the data information table is kept updated on each server node; on each server node, performing backup on query table corresponding to the actual query instruction so that query table copies are kept in each server node; on each server node, when concurrent conflict is detected, performing concurrent execution on actual query instruction through calling the query table copies on the current server node. By means of the data distribution and parallel processing method and system, the data consistency is guaranteed and the speed and efficiency of data query are increased as well.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a data distribution and parallel processing method and system. Background technique [0002] The method of parallel processing is a processing method that adopts parallel means in information processing to achieve efficient development and calculation. In other words, it refers to the completion of multiple tasks within the same time frame, which can be of the same or different nature. As long as there is overlap in time, it can be called parallelism. It is mainly used in high-performance processors, large-scale database management, complex mathematical modeling and other fields, and its application range is still expanding. It mainly includes three elements: simultaneity, concurrency, and flow. In order to achieve high performance and meet the needs of a large amount of calculation, a parallel computing model can be used for data processing. [0003] Big data...
