I've been thinking about adding full search support for OpenStreetMap. According to the Nominatim documentation, it says

A minimum of 2GB of RAM is required or installation will fail. For a full planet import 128GB of RAM or more are strongly recommended. Do not report out of memory problems if you have less than 64GB RAM. For a full planet install you will need at least 1TB of hard disk space. Take into account that the OSM database is growing fast. Fast disks are essential. Using NVME disks is recommended. Even on a well configured machine the import of a full planet takes around 2.5 days. When using traditional SSDs, 4-5 days are more realistic.

Honestly, that kind of scale just makes me want to try it
