Abstract

An embodiment of the invention provides a paging realization method. The method comprises the steps of receiving paging request information, wherein paging request data comprises a query SQL and check information of second data; judging whether a first cache stores the query SQL or not; retrieving the first cache according to the query SQL to obtain a first fragmentation index; judging whether a second cache stores the second data or not according to the check information; obtaining first data from the second cache; and obtaining the second data according to the first data, wherein the first fragmentation index includes at least one fragmentation index, the first cache stores a corresponding relationship between the query SQL and the first fragmentation index, the second cache stores the first data, and the first data is marked with one fragmentation index. Through combined use of the first cache and the second cache, the shortcomings of database paging and memory paging are overcome, the memory usage efficiency is improved, and a high-concurrent paging request is satisfied.

Description

technical field [0001] The invention relates to the field of computers, in particular to a paging implementation method and a paging system. Background technique [0002] With the rapid development of the Internet, the amount of information is increasing, and the data stored in some database tables has reached more than tens of millions. Facing such a huge data record set, it is impossible to display it on a single page within a limited page. Then there needs to be a way to provide fast and accurate paging display. [0003] Traditional paging techniques include two types: [0004] One is to paginate after all the data is loaded. This kind of paging usually uses the front-end paging control to perform paging, query all the data in the background and save it in the corresponding collection, and then transfer this data collection to the front-end paging control. This method is relatively simple to implement. The advantage is that the speed is fast, but the disadvantage is th...
