When a file is uploaded, the permission verification, read-write conflict verification and parameter verification are performed first, and then the file metadata is stored in the library. The storage scheme adopts the scheme of erasing the cache library first and then writing to the relational library to prevent the inconsistency between the two databases. Finally, send the synchronous upload information to the standby machine to synchronize the main and standby files.

The file downloading unit sends download related data to the server through the interface. When downloading a file, first perform permission verification, read-write conflict verification, and parameter verification, then query the metadata information of the file in the library, locate the file through the metadata, and return the file information. The database query solution adopts the method of first checking the cache library, then checking the relationship library, and refreshing the cache library to improve the response speed of the service.

The file deletion unit sends the file deletion information to the server through the interface. When deleting a file, first perform permission verification, read-write conflict verification, and parameter verification, query the metadata information of the file in the library, locate the file through the metadata, and delete the corresponding file and the metadata information of the file in the library. The deletion adopts the scheme of erasing the cache library first, and then erasing the relational library to ensure the consistency of the dual databases. After the deletion is completed, send the synchronous deletion information to the standby machine to complete the synchronous deletion of the active and standby machines.

The file query unit sends the conditions of file query to the server through the interface.
