Problems solved by technology

[0012] It can be seen from the above that the existing method of using the first-level index to write in reverse order, due to the characteristics of the micro-group, needs to write the latest data published by the user to the front of the data queue. Therefore, when the amount of written data (message When the amount) is large, each time new data is written, the data block occupied by the amount of written data needs to be moved back in the memory, which will consume a lot of kernel resources and be error-prone

Embodiment Construction

[0047] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0048]In the existing data reading and writing method based on index sorting, each time new data is written, the data blocks occupied by the amount of written data need to be moved back in the memory, resulting in a large amount of kernel resource consumption. In the embodiment of the present invention, considering the improvement of the existing index structure, the method of quick sorting of the secondary index is adopted, that is, the technology of secondary index caching is adopted, and the micro-group index is finely controlled in chronological order to form multiple storage The secondary index of the data block address ID information of the written data, so that when the data block corresponding to one of the secondary indexes is wri...

Abstract

The invention discloses a data reading-writing method and device based on index sorting. The method comprises the following steps of: receiving a data reading-writing request; according to a keyword carried in the data reading-writing request, matching a micro-cluster index table; obtaining a micro-cluster index corresponding to data to be written in; according to reading-writing time information carried in the data reading-writing request, obtaining secondary index address identification ID (identity) information corresponding to the reading-writing time information from the obtained micro-cluster index; according to the obtained secondary index address identification ID information, addressing a corresponding secondary index; obtaining the data block address ID of reading-writing data; and according to the obtained data block address ID, inverting the reading-writing data in the time sequence. When the invention is applied, the kernel resource consumption of the reading-writing data can be lowered.

Description

technical field [0001] The invention relates to computer data storage technology, in particular to a method and device for reading and writing data based on index sorting. Background technique [0002] With the development of computer network technology, instant messaging (IM, Instant Messaging) software tools for instant communication on the Internet through point-to-point technology are becoming more and more common. IM has been accepted by most users and has become a part of their daily life. As well as an essential part of work, through the application of IM software tools, such as Weibo, users can communicate with friends, colleagues and classmates. [0003] Micro-group is a communication platform for different user groups in Weibo. In Weibo, a group of people spontaneously join a small circle to communicate internally, and can choose to share part of the content with their own Weibo audience. . Due to the characteristics of the micro-group, the data published in the ...
