Abstract

The invention discloses a method for storing and querying Feed data and a device thereof. The method for storing and querying Feed data includes the following steps: segmenting the Feed data of each user, and each segment includes: first data, The second data and the third data form a linked list structure between each shard; each shard is stored in the storage system; when the user issues a query request for feed data, the current shard is obtained from the query request. The unique identifier is used to query the storage system using the unique identifier of the current shard as a keyword; and the third data in the shard where the second data that successfully matches the keyword is stored on the storage system is pointed to by the shard. The first data and the second data are returned to the user. The present invention is based on storing the feed content data in slices in the system, thereby reducing the number of queries that hit the feed content data. It improves the system's efficient reading and writing capabilities for small data blocks, effectively reduces the server's response time, and improves efficiency.

Description

technical field [0001] The invention relates to the field of data storage and query, in particular to a method and device for storing and querying Feed data. Background technique [0002] Feed data refers to the source of news, also known as source material, feed, information feed, feed, abstract, source, news feed, network source, etc. It is a data format through which websites can disseminate the latest information to Users, the prerequisite for users to be able to subscribe to the website is that the website can provide continuously updated information. News sources are widely used by blogs and news sites, as these types of sites are frequently updated. Feed flow presentation is that the user accesses the server through the client, and the data seen is sorted based on the timeline, that is, the data returned by the server must be greater than the time of the last request. Similar to domestic Weibo, foreign Twitter and so on. [0003] With the popularity of domestic Wei...
