File data reading and querying method and device and readable storage medium

Abstract

The invention discloses a file data reading and querying method and device and a readable storage medium. The method comprises the steps of obtaining text information; extracting required keywords inthe text information; judging whether value information corresponding to the extracted keyword exists in a key value pair database or not; if it is judged that the value information corresponding to the extracted keyword exists in the key value pair database, storing the keyword and the corresponding value information in an index file. According to the scheme, the index files are loaded into the internal storage, a large amount of data is stored into the index files firstly and then loaded into the internal storage at a time through the index files. Compared with a traditional mode that a large amount of data is read into the internal storage line by line, the scheme can accelerate the reading speed, and therefore the data reading time is shortened.

Description

technical field [0001] The invention relates to the technical field of file storage and reading, in particular to a file data reading and query method, device and readable storage medium. Background technique [0002] With the popularity of smart terminal devices, it is often necessary to read files in the device. When the data storage of the terminal device reaches a certain order of magnitude, the reading speed will be greatly reduced. For example, when there are 100,000 lines of data in a file, if each line of data is read line by line into the memory, 100,000 IO operations are required, which will take a long time to initialize the file data into the memory. It is an intolerable phenomenon in the device, resulting in a poor user experience. Contents of the invention [0003] The invention provides a file data reading and query method, device and readable storage medium, which have the characteristics of fast reading file data. [0004] The present invention provides ...
