Weekly update world osm mbtiles

[timprepscius]

Thank you for spending so much time on this project. I am using it at the moment to build the world. 16GB ram and 200GB "--store" space. Hopefully it will work.

I was wondering whether it would be possible to set up a weekly build of the world. Because:

1. You obviously have the machines to do it. I'm assuming you have a machine with a ton of ram.
2. There may be free options to host it.
3. This may be valuable in the future to see how cities and roads change over the years.

With #2 I'm referring to something like: https://archive.org/details/osm-vector-mbtiles

This would also serve as a test of your system to see if changes affect memory and cpu performance.

In any case- thank you again for your work on this project.

I like the idea. I couldn't really commit to doing it with my hardware though - the machine I have is actually here in my study and hence uses my home connectivity and power, rather than being colocated.

But it might be worth revisiting and looking at options when some of the work to reduce tilemaker's memory footprint (#499) is complete.

Great.

In my projects, I have found the xcode memory profiling tools to be excellent. (when compared to the linux assortment - I don't know about windows). You can also run Xcode from within a linux hosted osx docker via sickcodes.

I know this is a pretty random comment, however, understanding memory usage is sometimes non-trivial, and the tools can help a lot.

I wish you luck!
