Abstract

The invention discloses a big data query return method and device. The big data query return method comprises the steps of obtaining a corresponding start record number and a termination record numberbased on a query start time and a query termination time, wherein each query record has a corresponding record number, and the record number has an auto-increment attribute; determining a differencevalue of the termination record number and the start record number as the total number of the query records, and determining a quotient of the total number of the query records to the preset single-page number as the number of total pages; and returning to the corresponding query records in a paging mode from the start record number to the termination record number on basis of the single-page number and the number of the total pages. This method makes use of the auto-increment attribute of the record number to obtain the total number of the query records by means of the difference value of thetermination record number and the start record number, then determines the number of the total pages according to the total number of the query records and the preset single-page number, and returnsto all the query records that are queried in the paging mode so that the query return speed of tens of millions of the big data is effectively improved so as to better satisfy the user experience.

Description

technical field [0001] The present invention relates to the technical field of information retrieval, and more specifically, to a large data query return method and device. Background technique [0002] With the continuous development of informatization, the amount of data in each business system is getting larger and larger, and when the amount of data reaches a certain level, it is very time-consuming to query, especially when the data reaches tens of millions. If the database design is not reasonable , it often takes a long time to query more than tens of millions of data, and then displaying the queried data to users will cause a very bad user experience due to the long waiting time; therefore, improving the query of tens of millions of big data Return speed becomes even more important. [0003] How to give full play to the maximum performance of the system and make the query speed the fastest without increasing the hardware cost is a problem faced by many enterprises. ...
