Problems solved by technology

[0003] A large number of network input and output (IO) of distributed database systems come from cross-node data processing requirements. In this cross-node data processing, the delay of any node will greatly reduce the data processing efficiency of distributed database systems. resulting in a short-board effect

Abstract

The invention discloses a distributed data processing method and system. The method comprises the following steps: a service agent unit divides a task requesting processing into a plurality of sub-tasks, each of which only relates to a calculation task in one dimension; and a data node carries out data processing of a received sub-task in a corresponding network card. By dividing data nodes by different dimensions to process data of different dimensions respectively, the method reduces the network IO between the data nodes, improves the data processing efficiency across the data nodes, and thereby avoids the short board effect.

Description

technical field [0001] The invention relates to distributed technology, in particular to a distributed data processing method and system. Background technique [0002] In a distributed database system, data needs to be scattered and stored on multiple data nodes. Multiple data nodes have the ability to calculate and load data. Through distributed algorithms, the speed of database query or calculation in specific scenarios can be accelerated. However, for scenarios such as cross-node data analysis, because in the cross-node query or calculation, the operation of each data node must be completed before the results of the query or calculation can be combined, which will reduce the efficiency of data processing, thus forming a certain the bottleneck. For example: Take the query of users whose packages expire within one month in Shanghai as an example. Since the data is irregularly stored on 9 data nodes, it is necessary to query the users whose packages expire within one month ...
