Local computing and distributed computing based data computing method and system

The invention relates to a local computing and distributed computing based data computing method and system. The method comprises: calling preset local computing mode and distributed computing mode to compute a same data item, marking the computing mode with relatively short computing time as a preferred computing mode of the data item, and obtaining training samples each containing data volume, the preferred computing mode and computing time information; according to the training samples, generating a training model; and estimating the data volume of a to-be-processed data item, and according to the training model and the data volume of the to-be-processed data item, determining the computing mode adapting to the to-be-processed data item and calling the computing mode to compute the to-be-processed data item. Through the data computing method and system, computing policies adapting to the scales of data items can be selected for different data items, the realization cost is low, and the computing efficiency
