Data paging retrieval method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention provides a data paging retrieval method and device, electronic equipment and a storage medium, an index table is established for retrieval data conforming to retrievalconditions in advance, and when paging retrieval needs to be conducted on the retrieval data, only a target index conforming to retrieval parameters needs to be determined according to the retrieval table. The content block read from the data file through the target index is the target content block conforming to the retrieval parameter. During retrieval, only the retrieval parameters need to be matched with the retrieval table, the content blocks do not need to be matched with the retrieval conditions one by one, and repeated reading of the content blocks in the data file is avoided. And in the retrieval process, only the target index conforming to the retrieval parameters needs to be retrieved from the retrieval table, and all retrieval data does not need to be stored in the content, sothat memory overflow is avoided.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular, to a method, device, electronic device and storage medium for data paging retrieval. Background technique [0002] The retrieval of file content is a very frequent computer application scenario, such as finding all sentences containing a certain word from an article, or retrieving all error-level logs from the log files of a software system. Take the line-type log file as an example, the line-type means that each line is a complete content unit. In the log file, a line of content usually includes the occurrence timestamp, event source, information level, module, summary content, etc. of this log. , each line of content in the file is a complete content block, that is, a piece of data with business significance. If paging retrieval is performed on the log file, such as paging retrieval to retrieve all logs with the information level of "warning", the first is to load ...

Problems solved by technology

[0005] Embodiments of the present invention provide a method, device, electronic device, and storage medium for data paging retrieval, which are used to solve the problem of matching content blocks with retrieval conditions one by one and storing all matching rows when retrieving data in the prior art. to the memory, it is easy to cause memory overflow and the data in the content block is read too frequently
