Append mode, which adds new data to the end of a file. This mode is typically used for WAL. Flush mode, which flushes all data to one or more files and can specify the size of each file to write to. It will return an error when writing a directory, the file does not exist or there is not enough space, and the incomplete file will be discarded. +The following is the pseudocode that calls the API in the go style. +`writeFile(file File,data []byte) (error)` +`writeFile(files list,data []byte, int filesize) (error)` Review Comment: > Which is for the append mode? writeFile(file File,data []byte) (error) -- This is an automated message from the Apache Git Service.
