If I'm understanding the documentation right, `.lookup()` allows you to define the ""value"" column (the documentation uses name), but when you use `extracts` keyword as part of `.insert()`, `.upsert()` etc. the lookup must be done against a column named ""value"". I have an existing lookup table that I've populated with columns ""id"" and ""name"" as opposed to ""id"" and ""value"", and seems I can't use `extracts=`, unless I'm missing something...

A few different solutions I can think of: 1. Have some other endpoint, like `/-/datasette.json` that the Observable Datasette client can fetch from to verify that the passed in URL is a valid Datasette (doesnt solve the slow problem, feel free to split this issue into 2) 2. Have a way to turn off table counts when accessing a database's `.json` view, like `?no_count=1` or something 3. Maybe have a timeout on the `table_counts()` function if it takes too long. which is odd, because it seems like it already does that (I think?), I can debug a little more if that's the case More than happy to debug further, or send a PR if you like one of the proposals above!",107914493,issue,,,"{""url"": ""https://api.github.com/repos/simonw/datasette/issues/1111/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",, 534629631,MDU6SXNzdWU1MzQ2Mjk2MzE=,650,Add a glossary to the documentation,9599,open,0,,,3,2019-12-09T00:23:45Z,2022-01-13T22:04:56Z,,OWNER,,"Call it `glossary.rst` - it can use a definition list something like this: ```rst .. _glossary: Glossary ======== Term A definition of the term.
