Problems solved by technology

[0004] However, for sampling inspection, due to the existence of a certain sampling rate, it is extremely prone to data loss but cannot be detected
For the final consistency check, in the process of data transmission, data duplication often occurs. If there is no deduplication, the final number of records counted at the destination is inaccurate in many cases.
It can be seen that the detection accuracy of the above detection method for missing data is low

Embodiment Construction

[0041] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0042] refer to figure 1 , which shows a flow chart of the steps of an embodiment of a data detection method of the present application, which may specifically include the following steps:

[0043] Step 101, when synchronizing data of a specified file, obtain parameter information of the synchronous data, and the parameter information is associated with the synchronous data.

[0044] In the embodiment of the present application, the device for detecting whether data is lost (hereinafter referred to as the device) can be the target server itself when performing data synchronization, or a module set in the target server, or it can be independent of the target server. A device other than a server that can ...

Abstract

The embodiment of the invention provides a data detection method and device. The data detection method comprises the following steps of when the data of an appointed file is synchronized, obtaining the parameter information of the synchronized data, wherein the parameter information and the synchronized data are related; determining whether each piece of obtained parameter information corresponding to the appointed file has a vacancy or not; and if each piece of obtained parameter information corresponding to the appointed file has the vacancy, determining that the appointed file is subjected to data loss. By use of the detection method, the detection accuracy of lost data can be improved, a detection process is simple and easy in implementation, and detection efficiency is high.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a data detection method and a data detection device. Background technique [0002] In various web applications, there will be many log files continuously generated, such as buried logs used to record user behavior on the page. These logs are distributed on many servers, up to 10W servers, and there are multiple log files on each machine. In business, these log files need to be synchronized to the data warehouse system for analysis. Then, it is necessary to ensure that the data is not lost during the synchronization process, so as to provide real protection for the business. [0003] At present, during the synchronization process of massive data, there are two schemes for detecting whether data is lost. One is sampling inspection, which regularly outputs regular logs in the log, and then detects whether these regular logs exist at the destination (data warehous...
