This is consistent with how `?_next=` tokens work, e.g. `?_next=0.291861560261786%2Ce%2Cj`.

So the format can be:

- `mycolumn`
- `urlencoded-mycolumn$castname`

For most columns this will look like: `?_sort=score$numeric`

For columns with a `$` in their name it will be `?_sort=score%24hasdollar$numeric`

Problem: both `$` and `,` are usually URL encoded anyway. I need a character which isn't encoded by default, so that I can use its encoded form to show it is part of the column name and its un-encoded form to split the cast indicator.

`_` is a candidate here - not encoded by default, but can be encoded as `%5F`.

The other unreserved non-alphanumeric characters are `-`, `.`, `_`, `~`.

Of these, `~` is least likely to show up in a column name. So I'll use that.

If it's going to include sort by numeric options it needs a different format - since `?_sort=colname` needs to also support `?_sort=numeric_colname` - but shouldn't clash with a weird column already named `numeric_colname`.

Can I come up with a value syntax for this that is guaranteed not to clash with a weirdly named existing column?

I think so. I could use `{""type"": ""numeric"", ""column"": ""mycolumn""}` as the value - then if a column has a name that is itself valid JSON (weird but possible) the `_sort=` value would be `{""type"": ""default"", ""column"": ""{\""type\"": \""numeric\"", \""name\"": \""column\""}""}`.

Two options:

- Try to detect if a text column is all-integers or all-floats, either by scanning the entire table (if it's small enough) or by scanning the first X rows, where X might be the size of the first page or maybe the first 1,000 or similar.

One possible solution for the no-arbitrary-SQL case: users can define sort orders in `metadata.json/yml`. So if you want to enable sort-by-distance without enabling arbitrary SQL you could add something like this:
