Abstract

The present invention provides a metadata collection method and device, wherein the method includes: establishing a root directory, and creating a subdirectory for the data source under the root directory according to the unique identifier of the data source; creating a subdirectory for the subdirectory Generate a lock file, wherein the lock file includes at least the status of the lock file and the timestamp of the current task of collecting metadata; when the first file entry of collecting the metadata of the data source is detected through the subdirectory, An exclusive lock is added to the lock file; after the first file is entered, the exclusive lock is released, and the first file is transferred to the graph database for storage. The present invention can solve the problem of how to ensure data consistency in case of abnormal entry in the metadata collection process in the related art, and carry out metadata collection based on file locks to ensure data consistency.

Description

technical field [0001] The present invention relates to the monitoring field, in particular to a metadata collection method and device. Background technique [0002] For the metadata system based on outputting the metadata of the data source into a file in a specific format, and then parsing the file and entering it into the graph database, the conventional collection and entry control method is roughly based on the task scheduling system inside the system. The implementation of the system is multi-threaded scheduling, and the implementation details are to abstract the business logic, and implement concurrent scheduling through various locking mechanisms and concurrent programming. Although this method can meet business requirements, it also has many disadvantages, such as the scheduling method of the extended system is not flexible enough , and every time the function is expanded, the complexity of the system will be greatly increased, and the increase in complexity will br...
