Embodiment Construction

[0072] The present invention is described below based on examples, but the present invention is not limited to these examples. In the following detailed description of the invention, some specific details are set forth in detail. The present invention can be fully understood by those skilled in the art without the description of these detailed parts. In order to avoid obscuring the essence of the present invention, well-known methods, procedures, and flow charts are not described in detail. Additionally, the drawings are not necessarily drawn to scale.

[0073] In the prior art, when the processing server of various clients receives the data access request sent by the client, it first accesses the cache server, and then accesses the database server when the cache server has no data. The data query method of the processing server is in When the cached data in the cache server is public data and the data volume is large, the technical problem of slow response to data access re...

Abstract

The embodiment of the invention provides a data query method and system, and the method is applied to a processing server which processes data access requests of one type of clients, and comprises thesteps: receiving a data access request sent by any client in a preset client type, and enabling the data access request to be a request for obtaining target data; Querying a plurality of storage units according to the query priority to obtain target data, the plurality of storage units being arranged according to a descending order of the query priority as follows: a memory of a processing server, a cache server and a database server; And returning the obtained target data to the client. According to the embodiment of the invention, the memory of the processing server is added into the response mode of the data access request, and the maximum query priority is configured for the memory of the processing server, so that the task response pressure of the cache server is reduced, and the technical problem of relatively long response time of the data access request is solved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data query method and a data query system. Background technique [0002] With the development of the Internet, the number of visits to the database is also increasing. In order to reduce the access pressure of the database server, a cache server is usually set before the database server. When receiving an access request from the client for certain data, the current data query method is to first query whether the data exists in the cache server, and then query to the database server if it does not exist. [0003] In this current data query method, when the cached data is public data and the data volume is large (greater than 100 KB), it is very easy to have a long response time. Specifically, all clients will access the public cache, and the public cache corresponds to a cache key, and the cache key maps the access request of the public cache to the cache server that c...
