The embodiment of the present invention discloses a user portrait data query system, including: a first-level cache database, which caches the previous day's active user data stored in the dm data warehouse; a second-level cache database, which caches all users stored in the dm data warehouse Data; the data query module receives client query requests to query the required user data from the first-level cache database, the second-level cache database and the Metadata database; it is stored in a preset data storage structure, including: data description information and actual data, data The description information is an array containing multiple label objects, each label object includes field name and field type, all fields in the actual data are separated by separators, and the splicing order of the fields is consistent with the order of the label objects. The embodiment of the invention discloses a query method for user portrait data. The invention improves cache hit rate and query efficiency, and reduces data storage cost while supporting high concurrent access.
Description
technical field [0001] The present invention relates to the technical field of data processing, in particular to a query system and method for user portrait data. Background technique [0002] User portrait is the labeling of user information. By analyzing the data of various dimensions such as the user's basic information, feature preferences, and social attributes, it portrays the overall picture of the user's information and digs out valuable information from it. When realizing the online random query of user profile data, the query time is longer due to the large amount of data stored in the system, especially when massive data is accessed concurrently, the query efficiency is lower. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a user portrait data query system and method, which improves the cache hit rate and query efficiency, and reduces data storage costs while supporting high concurrent a...
