Problems solved by technology

However, Druid is a distributed data storage system that supports real-time analysis. When the amount of query data is relatively large, due to the large number of scanned partitions and many hit records, the memory is extremely occupied, resulting in a decrease in query performance.

Abstract

The embodiment of the invention provides a data query method and device, electronic equipment and a storage medium in the technical field of computers. The method comprises the following steps of obtaining a query request instruction according to the query request instruction; judging whether the quantity of the data uploaded by the target user is greater than a preset threshold value or not; if the quantity of the data uploaded by the target user is greater than the preset threshold value, determining that the target user is unloaded; obtaining the query content of the data to be queried froma ClickHouse engine, and if the quantity of the data uploaded by the target user is not greater than the preset threshold, obtaining query content of the to-be-queried data from a Duid engine, and combining the two query engines for use by utilizing the quantity of the data uploaded by the target user, so that the data query performance is improved, and the data query time is shortened.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to data query methods, devices, electronic equipment and storage media. Background technique [0002] In the era of big data, due to the continuous iterative update of data, users usually query the data stored in the system in the form of tables according to different needs. By querying massive data, it is convenient for users to make more informed business decisions . At present, data query is through Druid (a highly fault-tolerant, high-performance open source distributed system for real-time query and analysis of big data). However, Druid is a distributed data storage system that supports real-time analysis. When the amount of data queried is relatively large, due to the large number of scanned partitions and many hit records, the memory is extremely occupied, resulting in a decrease in query performance. Contents of the invention [0003] The purpose of the embod...
