By means of the steps, the number of copies of the sub-tree root in the distributed file system can be reduced, thereby reducing the number of interaction times of master copy locking between different MDSs, improving the file deletion efficiency, and improving user friendliness and differentiated competitiveness of a product."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method, apparatus and device for deleting distributed system file, and storage medium","description":"A method, apparatus and device for deleting a distributed system file, and a storage medium, comprising: querying whether an incomplete file deletion operation exists under a sub-tree root correspondi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-12001397","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
