Abstract

The embodiment of the invention discloses a memory data processing method and a storage medium, and relates to the technical field of computer data processing. The memory data processing method comprises the following steps: establishing a column type memory data structure, and configuring the memory data structure; selecting corresponding memory data structures according to the character string lengths of different types of data; performing memory management on different data types by adopting a column type storage management method; wherein a dynamic memory configuration strategy is adoptedto manage the data with the data length larger than a preset byte, and an inline storage management method is adopted to process the data with the data length smaller than the preset byte. The embodiment of the invention can solve the problem that the memory data structure in the prior art is poor in performance when processing mass data.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of computer data processing, and in particular to a memory data processing method and a storage medium. Background technique [0002] In existing database software and distributed data processing engines, it is necessary to design a data structure located in memory for storage, calculation and transmission of data based on the row-column relationship model. The design of the data structure and algorithm in memory directly affects the performance of the entire processing engine. [0003] However, the common relational database software used to process OLTP scenarios now usually uses row-by-row storage descriptions. In order to support practical processing, the data structure is nested and complex. For OLAP scenarios, a large amount of data needs to be processed, and the current data structure is not yet available. High performance, such as the existing distributed processing engines...
