Converting a continent sized MBTiles database like europe with about 21 gb takes only about 14 minutes.
But the conversion of a planet tileset with about 55 gb takes about 8 hours.
Task:

  • Improve query performance of the SQLIte database e.g. change database driver settings
  • Use prepared statements for the database queries
  • Use a worker pool to parallelize the conversion -> replace sqlite3 with better-sqlite3 for worker support
