Instead of having tons of different people trying to attempt loading all of
these 8 Million buildings, we shoul collectively start an import proposal
(OSM wiki, draft a plan, set up tasking managers, pre-process data, host
entire dataset, etc...).
The best/easiest solution we (OSM Ottawa) did for importing 1M+ buildings
was to convert the data into GeoJSON and then convert them into VectorTiles
using Tippecanoe  and host them using our own custom server (Micro Data
Service ) which hosts those vector tiles into OSM & GeoJSON. After all
the "hard work" is done.. you can simply add those small chunks of data
with JOSM using any Tasking Manager by adding the URL  in Extra
Instructions. An example of a final OSM tile would look like this  which
would be ready to import (semi-manually).
There's also integration with QA-Tiles  to prevent loading any duplicate
data (this feature requires continuously loading the most current QA-Tile
during the import process).
*Summary: *Before anyone attempts to import this data, we need to create a
plan first. I'm more than willing to help out, but this would be a large
task and would need to be done collectively as a group.
