Abstract

The application aims at providing a method and device for distributed diagram calculation. Compared with the prior art, the method provided by the invention comprises the following steps: firstly acquiring original diagram data, and processing the original diagram data according to a diagram algorithm to acquire structured diagram data corresponding to the diagram algorithm, thereby adapting to the diagram algorithms in different types; and then distributing the calculation tasks corresponding to the diagram algorithms to multiple calculation nodes to be executed, wherein a persistence condition should be satisfied in the execution process, the persistence operation is performed, the data dependence is cutoff, the repeated calculation amount is reduced, and the processing efficiency is improved. Furthermore, the application comprises firstly performing a combination operation on the diagram data before an aggregation operation and a connection operation, thereby improving the operation efficiency and relieving the network transmission pressure. Furthermore, the application adopts a data serialization and deserialization method to facilitate the transmission of intermediate data produced in the calculation process between the calculation nodes.
