@nitrag thanks for this contribution. It can take a while to download a file planet's worth of terrain tiles, so it's a great idea to parallelize that. We've got a number of other projects going so aren't able to work at the moment, but feel free to continue your PR and ping us when it's ready for a code review. |
…you need to download in batches because of storage limitations

This is probably not ready for an out-right merge but I want to bring it to you attention that it's possible to 10x the speed of tile downloads.
I'm able to achieve 450 tiles/sec (680Mbps) with this new method while downloading zooms 12, 13, 14 as separate commands. These stats are with an 8 CPU server, SSD (0% IO-Wait). So the limitation is my bandwidth.
Perhaps you want to incorporate this method into the larger download mechanisms.
