Abstract

The embodiment of the invention provides a distributed file cleaning method, device, and system, and is applied to the technical field of artificial intelligence. The method comprises the following steps: checking objects in a distributed file in a main hot cluster according to a configured data life cycle table, and determining to-be-processed objects; counting the to-be-processed objects; if the proportion of the number of the objects in the total number of the objects is greater than or equal to a preset proportion threshold value, marking the distributed file as a target cleaning file; according to the data life cycle table and a processing mode corresponding to a preset object state, cleaning objects in the target cleaning file according to the processing mode. Thus, HDFS files can be partially deleted, storage resources can be released, cluster storage spaces can be saved, and the storage cost can be reduced.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to the field of artificial intelligence technology, in particular to a distributed file cleaning method, device and system. Background technique [0002] Object storage is a technology often used in the Internet. In the object storage system, multiple objects are combined into one large file and stored in the Hadoop Distributed File System (HDFS for short), and each object The location information in the large file is written as an index in the distributed storage system (HBase). In the era of big data, the data in the object storage system grows extremely rapidly, and invalid or invalid objects in the system will occupy a considerable storage space. HDFS writes once and reads many times, which makes it impossible to partially delete HDFS files, resulting in a huge waste of cluster storage space and high cost of object storage systems. Contents of the invention [0003...
