Problems solved by technology

[0008] 1. When data rollback is required, the system generally needs to be re-launched, which takes a long time;
[0009] 2. The online server cluster needs to restart the service, which will cause some traffic loss;
[0010] 3. A large number of online servers pull data files from remote servers at the same time, which is prone to bandwidth bottlenecks and low efficiency

Abstract

The invention discloses a data updating method and device, and relates to the technical field of computers. A specific embodiment of the method comprises the steps of detecting whether to-be-updated data exists under a preset network disk path or not; when the to-be-updated data exists, downloading the to-be-updated data according to the network disk path and storing the to-be-updated data in a preset local data storage directory; and obtaining and loading the to-be-updated data from the local data storage directory to complete data updating. According to the embodiment, real-time updating andoff-peak downloading of the data can be achieved when the data updating operation needs to be executed, especially when the data rollback operation with the high time requirement needs to be executed, the data updating efficiency is greatly improved, data updating can be achieved without restarting service, and therefore flow loss is avoided.

Description

Technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for data updating. Background technique [0002] A lot of dynamic data is used in online services, such as word lists, model training files, and so on. When the data changes, the data is generally updated by updating the system version. If a problem occurs after the updated data is online, you need to perform a data rollback operation. The data rollback operation can also be considered as updating the currently used data to the previously used data again. Generally, if a problem occurs after the data is online, it should be handled quickly, otherwise it may cause serious losses. [0003] Currently commonly used online dynamic data rollback operations mainly include the following steps: [0004] 1. Obtain the remote download path of the dynamic data used by the online service according to the system configuration file, and modify the remote download path t...
