Abstract

The embodiment of the invention relates to the technical field of data processing, and discloses a data comparison method and a server. A data comparison method, comprising: reading two pieces of data in parallel; wherein each piece of said data contains a plurality of records and each said record forms a hash node; each said hash node is tried to be inserted into a hash tree In the process of trying to insert, if it is determined that there is a node matching the hash node in the hash tree, remove the node. The embodiment of the present invention also provides a server. The technical scheme of the embodiment of the present invention can efficiently process the comparison of a large amount of data, and effectively solve the bottleneck problem of the storage capacity of the Hash table in the comparison scheme.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data processing, and in particular to a data comparison method and server. Background technique [0002] In the process of bureau data synchronization, bureau data inconsistencies between systems often occur due to various reasons. For example, content interface information bureau data is synchronized by subsidiaries to the bureau data system, and then the bureau data system is synchronized to security control. There will be scenarios where the interface data between the subsidiary and the office data system, and between the office data system and the security control system are inconsistent. Therefore, it is necessary to compare whether the data of each network element is consistent. [0003] At present, when comparing whether the data of each network element is consistent, the first comparison data will be inserted into the first Hash table A, and then the second comparison dat...
