Example Embodiment

[0028] In order to make the purpose, technical solutions, and advantages of this application clearer, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the application, but not to limit the application.

[0029] figure 1 It is a schematic diagram of the internal structure of the terminal in an embodiment. Such as figure 1 As shown, the terminal includes a processor, a non-volatile storage medium, an internal memory and a network interface, a sound collection device, a speaker, a display screen, a camera, and an input device connected through a system bus. Wherein, the non-volatile storage medium of the terminal stores an operating system, and may also store computer-readable instructions. When the computer-readable instructions are executed by the processor, the processor may implement a data processing method. The pr...

Abstract

The invention relates to a data processing method and device, a storage medium and computer equipment, and the method comprises the steps of obtaining each node in to-be-processed data and node data corresponding to each node, and enabling the node data to comprise position information and node values; encoding each node and the node data corresponding to each node to obtain an encoding result; and if the node value of the node in the encoding result is empty, discarding the position information of the node from the encoding result, and marking the node as an empty column. According to the invention, the encoding and decoding efficiency of column storage of the nested data is improved, and memory resources occupied in the encoding process are reduced.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a data processing method, device, storage medium and computer equipment. Background technique [0002] With the continuous development of big data and the continuous integration of emerging technologies such as cloud computing, more and more data flows to the Hadoop ecosystem. products are becoming more and more important. During the rapid development of the Hadoop ecosystem, a number of open source data analysis engines have emerged, such as Hive, Spark SQL, Impala, Presto, etc., as well as multiple high-performance columnar storage formats, such as RCFile, ORC, Parquet et al. [0003] Parquet is a columnar storage format that supports nested structures and uses Dremel encoding. However, this encoding method has more redundant information, which causes problems such as low encoding and decoding efficiency. Contents of the invention [0004] Based on this, it is...
