The invention provides an expression-based big data processing method and device, an electronic device and a storage medium. The expression-based big data processing method comprises the following steps: parsing the expression into a tree structure, wherein a leaf node of the tree structure is a parameter type, and a parent node of the tree structure is a function type used for calculating a childnode of a subordinate; and recursive calculating from a leaf node having the longest path from the root node of the tree structure to the root node to obtain a calculation result of the expression. The method and the device provided by the invention can improve the expandability and the reusability of the expression.
Description
technical field [0001] The present invention relates to the field of computer application technology, in particular to an expression-based big data processing method, device, electronic equipment, and storage medium. Background technique [0002] With the rapid development of the Internet, the demand for big data computing continues to increase. There are many big data computing frameworks on the market, mainly divided into batch computing and streaming computing frameworks, which are also used in many existing applications. [0003] In existing big data computing, production work is usually carried out within the big data framework specifications and functions. However, this approach has the following drawbacks: [0004] 1) In big data computing, through direct reference between functions, functions customized according to special needs are not well isolated from other general functions, resulting in low operation and maintenance efficiency and low scalability and reusabil...
