Problems solved by technology

[0004] However, those skilled in the art know that when the application server needs to obtain data from the storage server, since the speed of reading data from the hard disk of the storage server is relatively slow, and each time it can only obtain the corresponding The data; that is, after obtaining the corresponding data according to the data identifier in one acquisition request, the corresponding data can be acquired locally according to the data identifier in the next acquisition request; thus, when receiving multiple When obtaining requests, it takes a lot of time to obtain the data corresponding to the data identifier in each obtaining request, resulting in low efficiency in obtaining data

Abstract

The present invention relates to a method and device for acquiring data, including: receiving multiple data acquisition requests; extracting data identifiers from each data acquisition request; When identifying the same data acquisition request, if there is no available data corresponding to the data identifier carried in the first data acquisition request in the at least two data acquisition requests in the local cache, according to the data identifier carried in the first data acquisition request, from the storage server Acquiring corresponding data; storing the acquired data in a local cache; acquiring corresponding available data from the local cache according to the data identification carried in the second data acquisition request in the at least two data acquisition requests. The invention can reduce the time spent in acquiring data, thereby improving the efficiency of acquiring data.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for acquiring data. Background technique [0002] The storage server includes multiple hard disks for storing data in the form of a database on the hard disks, and the application server is used for providing application services to clients used by users. For example, when the application server receives an acquisition request sent by a client for acquiring data, the application server sends the acquisition request to the storage server through the network connection with the storage server, and the acquisition request carries the data of the data to be acquired identification; the storage server receives the acquisition request, acquires the data corresponding to the data identification in the local database, and then returns the acquired data to the application server; the application server receives the data sent by the storage server, and returns...
