Abstract

The invention discloses a data query method and apparatus used for solving the problem that the system performance is affected by a large amount of blank query of a database in the prior art. According to the data query method, when a server receives a query request, the server determines whether the data corresponding to the data identification carried by the query quest exists or not only according to a pre-stored bloom filter, and the server finds and returns the data only when the data corresponding to the data identification carried by the query quest exists, without needing to query the data identification carried by each query quest, so that the blank query can be effectively filtered, and unnecessary pressure on the database caused by blank query is avoided; and therefore, the purpose of lowering the database expenditure and improving the query efficiency is improved.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a data query method and device in a high-concurrency scenario. Background technique [0002] With the rapid development of today's computer technology and Internet technology, people's daily life can no longer be separated from the Internet. More and more Internet products are well known to everyone and bring great convenience to people's work, life and study. [0003] At present, various information platforms need to be built on corresponding databases. For some popular websites, the number of visits to their backend servers is astonishing. At this time, in the face of a large number of query requests from users, the response of the server feedback query results is usually Create a delay. [0004] With the advent of the big data era, there will be more and more high-concurrency queries. When a large number of clients initiate query requests to the server within ...
