Embodiment Construction

[0038] In the data query process of the prior art, the database adopts the same splitting rules for the splitting of all users’ data query requests, without combining the user’s historical query behavior data, unable to consider the user’s data query requirements, and easily causing database failures. Stability, affecting the efficiency of data query.

[0039] Therefore, the embodiments of this specification provide a data query method, system, device, and electronic equipment, which determine the number of data query splits based on the query data volume within the query time range, and then split the data query based on historical query behavior data. The quantity is adjusted so that query results can be obtained quickly and data query can be realized. In this way, when the user's query data volume is too large and exceeds the database's bearing capacity, it can avoid the problem of query timeout that affects the user experience; in addition, by combining historical query behav...

Abstract

The embodiment of the invention discloses a data query method, system and device and electronic equipment, and the method comprises the steps: receiving a data query request carrying a user identifier, the data query request comprising a query time range; estimating the query data volume in the query time range; determining the splitting quantity of the data query request according to the query data quantity, so that the data query request is split according to the splitting quantity to obtain a query sub-request, and the query data quantity corresponding to the query sub-request does not exceed the database load for performing data query on the query sub-request; adjusting the splitting number by using historical query behavior data corresponding to the user identifier; and splitting thedata query request according to the adjusted splitting number, so that a database performs data query according to a query sub-request obtained according to the adjusted splitting number.

Description

Technical field [0001] The embodiments of this specification relate to the field of computer technology, and in particular to a data query method, system, device, and electronic equipment. Background technique [0002] Users will generate a variety of data in their daily lives. These data are stored in the database. For users who need to check the accuracy of the stored data, they often encounter situations where they need to query various stored data. . [0003] In the prior art, a user sends a data query request to a database through a terminal, and the database estimates the query data volume within the query time range corresponding to the data query request. If the query data volume within the query time range exceeds the database load, The data query request is split into multiple query sub-requests, and the database performs data query on the query sub-requests in sequence. Summary of the invention [0004] In view of this, the embodiments of this specification provide a da...
