The server processes the command and sends the response back to the client.
process client requests. The sub-process is responsible for writing memory content into temporary files; Because of the OS copy on write technology, when the parent process processes write requests, the OS creates a copy of the page to be modified, therefore, the address space data of the sub-process is a snapshot of the entire database at the fork moment; After the sub-process writes the snapshot to the temporary file, it replaces the original snapshot file with the temporary file, and then
