Problems solved by technology

[0002] Usually, real-time query requirements in big data scenarios involve real-time data and offline data query and multidimensional analysis. The applicable scenarios are relatively limited, and the correlation ability between tables is poor when the data of multiple tables needs to be obtained at the same time, which affects the efficiency of data query and increases the difficulty of complex data query

Abstract

Embodiments of the invention disclose a data query method and apparatus, and a computer readable storage medium. The method comprises the steps of obtaining a data query request submitted by a client; if the data query request carries a view name of a target view, performing reconstruction processing on the data query request to obtain a target query statement of at least one data table corresponding to the target view; using the metadata information in the data warehouse to analyze the target query statement to determine a query engine and a query rule, wherein the query engine is a distributed computing engine or a local computing engine; obtaining a data query result of the data query request from a target database in a data warehouse through a query engine and a query rule, sending the data query result to the client side, wherein the data warehouse comprises one or two of offline data and real-time data. By means of the data query method and device, synchronous query processing of offline data and real-time data can be achieved, the query difficulty of complex data is lowered, and the data query efficiency is effectively improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a data query method, device and computer-readable storage medium. Background technique [0002] Usually, real-time query requirements in big data scenarios involve real-time data and offline data query and multidimensional analysis. The applicable scenarios are relatively limited. When the data of multiple tables needs to be obtained at the same time, the correlation ability between the tables is poor, which affects the efficiency of data query and increases the difficulty of complex data query. Contents of the invention [0003] Embodiments of the present application provide a data query method, device, and computer-readable storage medium, which can realize synchronous query processing of offline data and real-time data, reduce the difficulty of complex data query, and effectively improve the efficiency of data query. [0004] On the one hand, an embodiment of th...
