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 present invention relates to the field of computers, in particular to a paging realization method and paging system. Background technique [0002] With the rapid development of the Internet, the amount of information is getting larger and larger, and the data in some database storage tables has reached tens of millions of levels. Faced with such a huge data record set, it is impossible to display one page in a limited page. Then there needs to be a way to provide fast and accurate paging display. [0003] Traditional paging technologies include two types: [0004] One is to page after all the data is loaded. This kind of paging usually uses the front-end paging control for paging, and all the data in the background is queried and saved in the corresponding collection, and then the data collection is passed to the front-end paging control. This method is relatively simple to implement. The advantage is that it is fast, but the disadvantage is that when th...
