I think I have an alternative suggestion for what you need to do here. It sounds to me like you need to calculate a specific piece of information against a specific database. Instead of doing this in inspect, how about having a separate tool which runs this once against the database file and writes the result into a database file there?

I've been thinking about this pattern a bit as part of the sqlite-utils work I've been doing. It's already something that's needed for SQLite FTS support - it's no good just creating a FTS index, you have to populate it as well. In sqlite-utils world you do that like this: https://sqlite-utils.readthedocs.io/en/latest/cli.html#configuring-full-text-search

    $ sqlite-utils enable-fts mydb.db documents title summary

But then later if you've inserted new records you have to call this:

    $ sqlite-utils populate-fts mydb.db documents title summary

So one option here could be for `datasette-geo` to know to look for a special `datasette_geo_bounding_box` database table and, if it's missing, to calculate at runtime (probably once on startup and then cache it).

Another option: Datasette now has an option to open a database file in ""immutable"" mode, using `datasette -i mydatabase.db`. When you do that we calculate counts on startup - and we'll also be able to load counts from the `inspect-data.json` file (that's pretty much all that will be in there). I'm open to making this available as a plugin hook - all kinds of optimizations could be run against these `-i` databases. It would essentially be what we have with inspect today but just for databases opened in that specific mode.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",421551434,
