文件处理方法及电子设备
By introducing a globally unique and monotonic sequence number mechanism into the distributed file system, the problem of duplicate file deletion is solved, achieving highly robust and flexible file deletion, while reducing the dependence on the underlying storage and the overhead of metadata storage.

AI Technical Summary
In existing distributed file systems, the two-phase deletion mechanism may cause the same file to be repeatedly appended to the cleanup queue after a system failure, resulting in data being deleted incorrectly or failing to be deleted. This increases the implementation complexity of the underlying storage and limits the flexibility of the system architecture.
A globally unique and monotonic sequence number mechanism is introduced. By assigning a unique sequence number to each file deletion request and establishing a mapping relationship with the inode, combined with memory mapping and log persistence, the idempotency control of file deletion requests is ensured.
It effectively intercepts duplicate deletion requests for the same file, reduces the complexity of the underlying storage implementation, improves the flexibility of the system architecture, and minimizes metadata storage overhead while ensuring state recoverability, thus achieving highly robust and flexible distributed file deletion.
