Abstract

The invention provides a data processing method, device and equipment, and the method comprises the steps: obtaining an original execution plan which comprises a plurality of nodes; selecting a targetnode which cannot be processed by a data source from the nodes of the original execution plan; performing equivalent transformation on a target node in the original execution plan to obtain an equivalent execution plan; determining a target execution plan according to the original execution plan and the equivalent execution plan; and sending the target execution plan to a data source, so that thedata source executes the target execution plan. Through the technical scheme of the invention, the computing power of the data source can be reasonably utilized, the data transmission quantity is reduced, and higher query performance is obtained.

Description

technical field [0001] The present application relates to the technical field of the Internet, and in particular to a data processing method, device and equipment. Background technique [0002] Currently, data is usually stored in multiple data sources (that is, databases). For example, some data of an enterprise is stored in data source 1, and another part of data is stored in data source 2. Since the data is scattered and stored in different data sources, it is necessary to connect each data source through the query system and read data from each data source to support data processing across data sources. For example, the query system can read data from data source 1, read data from data source 2, and use the read data for processing. [0003] However, if the query system reads all the data in data source 1 and reads all the data in data source 2, the cost of data reading is high, which ultimately affects the overall processing efficiency of the query system. Based on th...
