Problems solved by technology

[0003] In the prior art scheme, the client first sends out the query conditions, and after the server receives the query conditions, it assembles the query conditions into a structured query language SQL (Structured Query Language), and then transmits them to the database. After extracting the data, the query result is returned, and the server reorganizes the query result and passes it to the client. However, in this solution, when there are a lot of query results and frequent concurrent queries, the query pressure on the database will be very high, and it is impossible to do to quick response

Embodiment Construction

[0013] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0014] The method described in the embodiment of the present invention is aimed at the real-time monitoring system, and the query period from the client to the server is incremental, and the query range of time must be within the time period of the hot data life cycle. Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings, as figure 1 Shown is a schematic flowchart of a method f...

Abstract

The invention discloses a method for querying hot data. The method comprises the following steps that, firstly under a real-time monitoring system, a server end queries the hot data in advance, and the queried data is cached in the internal storage of the server end; when a client queries hot data, the server end can execute data query operation in a pre-cached data; a query result is returned to the client. According to the method, query efficiency and response speed of the client can be improved, and query pressure of a database is reduced.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method for querying hot data. Background technique [0002] At present, in the real-time monitoring system scenario, usually only the business data of the latest time period is concerned. According to business needs, it can be the data of the last 30 minutes, the last hour, or even the last few hours. This part of the concerned data can be It is called hot data, and when hot data loses its timeliness, it is called cold data. Over time, hot data becomes cold and the most recently received data becomes hot. The real-time monitoring system often needs to perform frequent queries on hot data, and such queries require quick response so that they can be displayed in the real-time monitoring system in a timely manner. [0003] In the prior art scheme, the client first sends out the query conditions, and after the server receives the query conditions, it assembles the query c...
