Abstract

The invention discloses a method and system for querying demand information based on a distributed database. The method includes acquiring query keywords; acquiring query information in a distributed database according to the query keywords; querying information in the distributed database including keyword-containing content information and keyword-related content information; constructing a multiple hash ring according to the query keyword and query information in the distributed database; the multiple hash ring is used to convert the query The keywords are arranged corresponding to the query information in the distributed database; the to-be-queried keywords input by the user are acquired; and the query information corresponding to the to-be-queried keywords is acquired according to the multivariate hash ring. The invention provides a method and system for querying information based on distributed database requirements, which improves the real-time performance of information querying in the distributed database, and further improves the information query efficiency.

Description

technical field [0001] The present invention relates to the technical field of distributed databases, in particular to a method and system for querying demand information based on distributed databases. Background technique [0002] With the advancement of information technology and the continuous development of society, the application of big data is not in-depth, and people's demand for data query continues to grow. From centralized databases to distributed databases, changes in data query technology have made it possible to build large-scale data query systems. In order to meet the needs of data query, distributed databases have been developing and popularizing rapidly, and new technologies are emerging. [0003] In a narrow sense, a distributed database refers to the decentralized storage of data in a centralized database on multiple storage nodes connected through a network to obtain larger storage space and higher concurrent access. It has the advantages of flexibili...
