Abstract

The application discloses a task processing method and device. A specific implementation of the method includes: analyzing the expression corresponding to the calculation task, determining the data index, the operation to be performed on the data belonging to the data index, the data index and the operation parameter corresponding to the operation; obtaining the time in the geographical scope and the operation parameter The data corresponding to the union of segments; perform operations on the data corresponding to the operation parameters in the data. It realizes one-time parsing of the expressions of computing tasks, determines each operation and the data required by each operation, and constructs a computing context. Query all the data required for computing tasks at one time to improve computing efficiency. At the same time, the query is performed after merging the parameters associated with the data to be queried, avoiding the problem of repeatedly reading data during task processing, and reducing the overhead of data storage. After obtaining the data required by all computing tasks, operations can be performed in parallel to further improve computing efficiency.

Description

technical field [0001] The present application relates to the field of computers, in particular to the field of data analysis technology, especially to a task processing method and device. Background technique [0002] In the data analysis of massive data (such as data mining), it is often necessary to calculate the statistical characteristics of the data (such as year-on-year, ring-to-ring) to achieve better and more intuitive statistical analysis results. At present, the commonly used method is: generate calculation tasks represented by expressions, serially analyze the keywords representing operations in the expressions of calculation tasks, and determine each operation in the calculation tasks (such as year-on-year calculation, ring-to-ring calculation) and the data required for each operation. [0003] However, when computing tasks are processed in the above manner, there is a large amount of duplication of data required by each operation, and it is necessary to read t...
