Problems solved by technology

[0004] Another way is to generate a data query request for any index of the database, and a single thread executes the data query request to export the data corresponding to the index. Compared with the above method, although there is no need to send data query requests frequently, a large amount of data is passed through a single Thread export, reducing data export efficiency

Embodiment Construction

[0046] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0047] See figure 1 , which shows an optional flow of a data export method provided by the embodiment of the present application. Multiple data query requests processed in parallel are obtained by reconstructing the data query request, so that a data query request can be sent once for any database. Improve data export efficiency without increasing lo...

Abstract

The invention provides a data exporting method and device, electronic equipment and a storage medium, after a first data query request carrying a first data selection condition is obtained, the first data selection condition is extracted from the first data query request, the data query request is reconstructed according to the first data selection condition and a preset reconstruction condition, and the reconstructed data query request is sent to the storage medium. The method comprises the following steps: acquiring at least two second data query requests, and processing the at least two second data query requests in parallel to export data corresponding to the at least two second data query requests, so that the first data query request can be sent once for any database; and the plurality of second data query requests constructed by the first data query request are utilized to export the data in parallel, so that the data export efficiency is improved on the basis of not increasing the load.

Description

technical field [0001] The present application belongs to the technical field of data processing, and in particular relates to a data export method, device, electronic equipment and storage medium. Background technique [0002] With the development of computer information technology, search servers can provide data storage services and engine services, such as Elasticsearch (a search server based on Lucene) can store data and provide engine services, and the data stored in search servers should be used for data backup or data exchange business Needs to be exported from the search server. [0003] At present, there are two ways to export data from the search server: one way is to generate multiple data query requests corresponding to the database in the search server, send data query requests to the database in sequence, and export and data query each time a data query request is received. Query the data matched by the request. This method requires frequent data query reques...
