Problems solved by technology

[0004] However, with the continuous development of business, the access volume of the query service to the front-row data is also increasing. At this time, due to the hardware limitation of the network bandwidth, it cannot meet the requirements of successfully accessing a large amount of front-row data under low latency. Excessive row data access will lead to corresponding query performance bottlenecks

Embodiment 1

[0029] figure 1 A schematic diagram of a data query system provided by Embodiment 1 of the present invention. This embodiment is applicable to querying published data in any business scenario, for example, in a resource recommendation service, it is necessary to query various multimedia resources that have been published by each user. Specifically, refer to figure 1 , the data query system may include: an online query library 110 , a data update queue 120 and an online query service 130 .

[0030] Wherein, the online query database 110 stores the online data set to be queried, and deploys it in the local memory of the online query service 130, and the data update queue 120 stores the update log of the online data set; specifically, the online query service 130 updates the queue 120 according to the data The update log in correspondingly updates the online data set in the online query library 110, and when a data query instruction is received, the online data set in the onlin...

Embodiment 2

[0045] figure 2 It is a schematic structural diagram of a data query system provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the technical solutions provided by the above embodiments. refer to figure 2 , the data query system may include an online query library 210 , a data update queue 220 and an online query service 230 .

[0046] Wherein, the online query library 210 stores the online data set to be queried, and deploys it in the local memory of the online query service 230, and the data update queue 220 stores the update log of the online data set; specifically, the online query service 230 updates the queue 220 according to the data The update log in correspondingly updates the online data set in the online query library 210, and when a data query instruction is received, the online data set in the online query library 210 is queried through the local memory.

Abstract

The invention discloses a data query system, a data query method, a data query device and a server. The system comprises an online query library, a data updating queue and an online query service; theonline query library stores an online data set to be queried and is deployed in a local memory of the online query service, and the data updating queue stores an updating log of the online data set;and the online query service correspondingly updates the online data set in the online query library according to the update log in the data update queue, and queries the online data set in the onlinequery library through a local memory when receiving a data query instruction. According to the technical scheme provided by the invention, the accuracy of the query data in the online query library is ensured, the problem of query performance bottleneck caused by network bandwidth limitation when the to-be-queried data is accessed through the network is avoided, the network access query is converted into the local memory access query, the access delay of the data query is greatly reduced, therefore, the data query efficiency is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data processing, and in particular, to a data query system, a data query method, device, and server. Background technique [0002] With the rapid development of Internet technology, there is a large amount of Internet data in different business scenarios in the Internet field to recommend high-quality content to other users, such as the push of multimedia resources such as dynamic, video, and audio published online. At present, in the recommendation system, the method of key-value pair (key-value) is usually adopted, and the candidate identifier (such as the candidate ID number, etc.) of each recommended candidate is used as the key value, and all the recommended candidates The descriptive information (such as the publisher of the recommended candidate, the release time, the number of current browsing or viewing, etc.) is used as the specific value content under the key value, so...
