Abstract

The invention provides a data updating and query control method and system. The method comprises the following steps: merging updated data received by a memory area into any one of two hard disk areas, and emptying the updated data stored in the hard disk after merging is completed; and returning the data of the hard disk area which does not execute merging operation in the two hard disk areas and the data of at least one memory area in the memory areas to a data querier. In the invention, the two hard disk areas are utilized to respectively execute the merging and query of the updated data to realize separation of query operation and updating operation, thus the instantaneity and system complexity problems caused as a locking policy is required to be set in the prior art are solved.

Description

technical field

[0001] The invention relates to the field of data storage, in particular to a data update and query control method and system. Background technique

[0002] For the data storage module, ensuring the real-time performance of the system and the accuracy of the data has always been a key issue. Considering stability and data accuracy in existing businesses, many systems rely on database products. Generally speaking, there is no big problem for a system to provide queries or updates alone, but if a single system has to deal with a large number of simultaneous updates in the case of a large amount of concurrent queries, then there will be queries Real-time, update immediacy issues. At the same time, the database considers more versatility, resulting in a greater loss of efficiency, and the disk random I / O pressure is high when faced with a large number of updates. With the growth of the data scale, it is difficult to meet the performance requirements of the appl...
