Embodiment Construction

[0055] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0056] figure 1 It is a schematic structural diagram of a data query system shown according to an exemplary embodiment. based on figure 1 As shown in the data query system, the embodiment of the present disclosure implements a data query solution with high performance and millisecond-level response speed in the environment of heterogeneous data sources and massive data. That is, the...

Abstract

The disclosure relates to a data query method and system, and belongs to the technical field of databases. The data query system includes a data processing engine, a query engine, and a storage engine. The query engine includes a cache; the data processing engine is used to receive data from heterogeneous data sources, and filter the received data based on a pre-built data dictionary; data processing The engine is also used to perform multi-dimensional aggregation operation processing on the filtered data, and store the obtained data processing results in the cache or storage engine; the query engine is used to judge the data query request when receiving the data query request from the terminal Whether to hit the cache, if the data query request hits the cache, obtain the query result matching the data query request from the cache and return it to the terminal; if the data query request misses the cache, obtain the query result from the storage engine and return it to the terminal. The disclosure realizes fast data query in complex business scenarios of multi-source heterogeneous massive data.

Description

technical field [0001] The present disclosure relates to the technical field of databases, in particular to a data query method and system. Background technique [0002] The advent of the information age has led to an explosive growth of data, such as the query demands of TB (terabyte) or even PB (petabyte) level big data, which has far exceeded the query capabilities of traditional computing technologies and information systems , when faced with massive data queries, it is difficult for the data query system to return matching query results within a time acceptable to the user, that is, it is difficult for the data query system to meet the user's requirements for query response time. Based on this, in a massive data environment, how to implement data query to reduce query response time and improve query performance has become an urgent problem to be solved by those skilled in the art. Contents of the invention [0003] The present disclosure provides a data query method ...
