Embodiment Construction

[0043] Aiming at the problem in the prior art that the data processing performance of the system is degraded when a large number of cache misses occur, the embodiment of the present application provides a data acquisition method. When the user acquires data content through the client, the key Words are filtered, and only when it is determined that the keyword exists in the system will it reach the cache for data query, thereby increasing the probability of a cache hit.

[0044] The data acquisition method provided by the embodiment of the present application, its process is as follows figure 2 As shown, the execution steps are as follows:

[0045] Step S11: the client sends a data acquisition request to the application server.

[0046] The user uses the client to send a data acquisition request containing selected keywords to the application server in the application system.

[0047] Step S12: the application server judges whether the keyword carried in the data acquisition...

Abstract

The invention discloses a data acquisition method, system and device. The data acquisition method comprises the following steps of: receiving a data acquiring request sent by a client side; judging whether keywords carried in the data acquiring request are in a preset white list; when the keywords are not in the white list, informing the client end of not finding data contents corresponding to the keywords; when the keywords are in the white list, querying a cache according to the keywords, and querying a background database so as to acquire the data contents corresponding to the keywords when the data contents corresponding to the keywords cannot be found in the cache; when the data contents corresponding to the keywords are found, providing the found data contents for the client side; and when the data contents corresponding to the keywords are not found, informing the client side not finding the data contents corresponding to the keywords. According to the data acquisition method, system and device, data requests are filtered through the set white list, therefore the condition of great hitting incapability of the cache is avoided, and the data processing efficiency and the system reliability are improved.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a data acquisition method, system and device for Internet website data acquisition. Background technique [0002] With the rapid growth of Internet users, the number of visits to Internet applications has also experienced rapid growth. Huge access traffic will put huge pressure on the back-end systems of the Internet, such as databases or other back-end services. For some website systems with a large number of visits, the data reading frequency is much higher than the data update frequency. In order to improve the throughput of the system, at present, most of them use local cache or centralized cache based on keywords and key values ​​(key / value) to cache some data, so as to reduce the pressure on the back-end system and improve the throughput of the website system. [0003] In the prior art, the process of applying cache to realize data request is as follows: ...
