Q: Why are results blank or incorrect after the FastDFS map tiles are exported to MBTiles?
A: Export the MBTiles file when the FastDFS map tile set is being written and the result may not contain the latest tile result. If the map tile set is the first time to be written, the exported MBTiles may appear blank; If it is not the first time, the exported MBTiles file will not contain the latest results, resulting in the incorrect tiles.
So please export the MBTiles file after the FastDFS map tiles are written.
