en.osm.town/@jez@mapstodon.spa Jez asks if PMTiles could be updateable. Here's my view:

* Separate tiles or metatiles (8x8): wastes a lot of space because of inode usage and internal fragmentation, but it's updateable by .

* : Saves space, updates possible by reimplementing rsync for SQL, leads to internal fragmentation, which can be removed via vacuum, but requires double the space.

* : Saves all space, but not updateable rsync-like, you have to push all data again.
