Abstract

The embodiment of the invention discloses a data query method and a device, a storage medium and electronic equipment. The data query method comprises the steps of when a data query request is received, determining a first sheet key and a query condition according to the data query request; determining a first fragment corresponding to the first fragment key from a fragment cluster, determining atarget balance tree matched with the query condition from a plurality of balance trees stored in the first fragment, and storing non-leaf nodes in a memory; searching the target balance tree layer bylayer to obtain a first index meeting a query condition and data record information associated with the first index from the leaf node; and obtaining first data corresponding to the first index from the first fragment according to the data record information, and responding to the data query request based on the first data to realize efficient query of the data.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data query method, device, storage medium and electronic equipment. Background technique [0002] For systems that need to store the data uploaded by users and provide users with data query based on data attributes, the usual practice is to store the data uploaded by users in the database. Attributes are used as conditions to query and filter the database to obtain the required data. [0003] However, in the data storage method provided by the above solution, when performing data query, it is necessary to traverse all the data in the database to obtain the query result, and the query efficiency is low. Contents of the invention [0004] Embodiments of the present invention provide a data query method, device, storage medium, and electronic equipment, aiming at improving data query efficiency. [0005] An embodiment of the present invention provides a data query meth...
