Embodiment Construction

[0038] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0039] The operation log-based model data recovery method provided by the embodiment mainly includes three parts. The first part is to establish a notification mechanism on the underlying model network for capturing log information during model operation; the second part is to establish an efficient persistence mechanism. to access the model operation log information generated in the notification mechanism; the third part is the specific data recovery process, which is used to read the log information of the persistent medium and perform corresponding processing to a...

Abstract

The invention discloses a method for restoring model data based on operation logs. The method for restoring model data includes: constructing a log system based on modeling operation records; Modeling operation messages are organized as a log persistence unit with all modeling operation messages within the time period from the modeling operation request to the response to the modeling operation request; each log persistence unit is persisted into the log persistence engine; When data is restored, the log persistence units are read sequentially to form a time series-based modeling operation record set. The model data restoration method can realize the restoration of model data.

Description

technical field [0001] The invention relates to the technical field of data recovery, in particular to a model data recovery method based on an operation log. Background technique [0002] Model data recovery is mainly used in the two scenarios of modeling transaction rollback and model data loss, and is a must-have function in complex modeling systems. It guarantees the integrity and correctness of data and provides backup for important data. During the modeling process, modelers perform model operations in custom-scoped transactions. Once the transaction needs to be canceled, or is terminated abnormally, the model data needs to be restored to the state at the beginning of the transaction. This situation can arise from a normal cancel operation, or from a failure or exception. Among them, the failure may be caused by software and hardware damage such as process crash, network disconnection, disk bad sectors, etc., and after operations such as division by 0, array overflo...
