I was able to find all 10 Whole Foods in the City of Chicago in 22.6s with DuckDB. It's amazing! (there are tons more Whole Foods in the metro area, but it found the exact 10 in the city) SELECT
tags['addr:city'][1] city,
tags['addr:state'][1] state,
tags['brand'][1] brand,
*,
FROM st_readosm('us-latest.osm.pbf')
WHERE 1=1
and city = 'Chicago'
and state = 'IL'
and brand = 'Whole Foods Market'
I'm sure there are ways to make this faster (partitioning, indexing, COPY TO native format, etc.) but querying a 9.8GB compressed raw format file with data (in key-value fields stored as strings) for the entire United States at this speed is pretty impressive to me. |

When I index the entire United States, admittedly with a subset of tags, I can search in milliseconds. I'll take it.
