Abstract

The embodiment of the invention provides a data processing method and device, a resource allocation method and device, equipment and a readable storage medium. The data processing method comprises the steps that N input data tables storing multiple pieces of data are obtained, the N input data tables are connected according to a preset connection sequence, and N is a positive integer larger than 1; elements in the M element groups in the N input data tables are converted into conversion values with the same length, so that N conversion tables comprising the conversion values are obtained, and M is a positive integer larger than 1; the method also includes performing parallel access on the driving elements in the driving table at the most front end of the preset connection sequence in the N input data tables, and performing parallel query on the conversion tables of the input data tables except the driving table in the N input data tables according to the preset connection sequence based on the conversion values of the driving elements; and generating an output data table based on the parallel query result. According to the embodiment of the invention, the efficiency of multi-table connection query can be improved through the conversion values with the same length and parallel query.

Description

technical field [0001] The embodiments of the present disclosure relate to the field of computer technologies, and in particular, to data processing and resource allocation methods, devices, equipment, and readable storage media. Background technique [0002] In database usage scenarios, multi-table join query is a very critical and extremely frequent query scenario. This kind of query involves a large amount of data and complex calculations, so the query time is long, and the query results are usually obtained by offline calculation, which cannot meet the needs of real-time interactive query analysis. Contents of the invention [0003] In order to solve problems in related technologies, embodiments of the present disclosure provide data processing and resource allocation methods, devices, devices, and readable storage media. [0004] In the first aspect, an embodiment of the present disclosure provides a data processing method, including: [0005] Obtaining N input data...
