The problem there is that `?_size=x` isn't actually doing the same thing as the SQL `limit` keyword. Consider this query:
https://latest-with-plugins.datasette.io/github?sql=select+*+from+commits - `select * from commits`
Datasette returns 1,000 results, and shows a ""Custom SQL query returning more than 1,000 rows"" message at the top. That's the `size` kicking in - I only fetch the first 1,000 results from the cursor to avoid exhausting resources. In the JSON version of that at https://latest-with-plugins.datasette.io/github.json?sql=select+*+from+commits there's a `""truncated"": true` key to let you know what happened.
I find myself using `?_size=2` against Datasette occasionally if I know the rows being returned are really big and I don't want to load 10+MB of HTML.
This is only really a concern for arbitrary SQL queries though - for table pages such as https://latest-with-plugins.datasette.io/github/commits?_size=10 adding `?_size=10` actually puts a `limit 10` on the underlying SQL query.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",627794879,

This is something I've not thought very hard about. If there's an error, I need to return a top-level object, not a top-level array, so I can provide details of the error.
But this means that client code will have to handle this difference - it will have to know that the returned data can be array-shaped if nothing went wrong, and object-shaped if there's an error.
The HTTP status code helps here - calling client code can know that a 200 status code means there will be an array, but an error status code means an object.
If developers really hate that the shape could be different, they can always use `?_extra=next` to ensure that the top level item is an object whether or not an error occurred.

One implementation that could be nice is that each of the keys that can be requested - `next_url`, `total` etc - maps to an `async def` function which can do the work. So that expensive `count(*)` will only be executed by the `async def total` function if it is requested.
This raises more questions: Both `next` and `next_url` work off the same underlying data, so if they are both requested can we re-use the work that `next` does somehow? Maybe by letting these functions depend on each other (so `next_url()` knows to first call `next()`, but only if it hasn't been called already.

To get the version that includes pagination information you would use the `?_extra=` parameter. For example:
`/fixtures/roadside_attractions.json?_extra=total&_extra=next_url`
```json
{
""rows"": [
{
""pk"": 1,
""name"": ""The Mystery Spot"",
""address"": ""465 Mystery Spot Road, Santa Cruz, CA 95065"",

],
""total"": 4,
""next_url"": null
}
```
ANY usage of the `?_extra=` parameter would turn the list into an object with a `""rows""` key.
Opting in to the `total` is nice because it's actually expensive to run a count, so only doing a count if the user requests it feels good.
But... having to add `?_extra=total&_extra=next_url` for the common case of wanting both the total count and the URL to get the next page of results is a bit verbose. So maybe support aliases, like `?_extra=paginated` which is a shortcut for `?_extra=total&_extra=next_url`?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",627794879,

That's not ideal. I'd like custom renderers to be able to access this data to get at things like suggested facets, on an opt-in basis.
So maybe that kind of stuff is re-implemented as ""extras"" which are awaitable callables - then renderer plugins can call the extras that they need to as part of their execution.

Arguments in favour of a list:
- It's what I always want. Almost all of the code that I've written against the API myself uses `?_shape=array`.
- It's really easy to use. You can pipe it to e.g. `sqlite-utils insert`, you can load it into JavaScript without thinking about it.
Arguments against:
- Nowhere to put pagination or total counts. I added pagination to the `link:` HTTP header in #1014 (inspired by the WordPress and GitHub APIs) but I haven't solved for total count, and there's other stuff that's useful like `""truncated"": true` to indicate that more than 1000 results were returned and they were truncated.
- An array is inherently non-extensible: if the root item is an object it's easy to add new features to it in a backwards-compatible way in the future. An array is a fixed format.
But maybe that last point is a positive? It ensures the default `.json` format remains completely predictable forever.
If `.json` DID default to an array of objects, the `?_shape=` argument could still be used to get back alternative formats.
Maybe `.json?_extra=total` changes the shape of that default to be this instead:
```json
{
""rows"": [{""id"": 1}, {""id"": 2}],
""total"": 104
}
```
The thing I care about most though is `next_url`. That could be provided like so:
`.json?_extra=total&_extra=next` - alternative syntax `.json?_extra=total,next`:
```json
{
""rows"": [{""id"": 1}, {""id"": 2}],
""total"": 104,
""next"": ""2"",
""next_url"": ""/db/table.json?_extra=total&_extra=next&_next=2""

Alternative shapes would provide the pagination information (and other extensions) in the JSON, e.g.:
`/squirrels/squirrels.json?_shape=paginated`
```json

""pk3"": ""a"",
""content"": ""a-a-a""

""pagination"": {

There's a lot of stuff in there. This increases the risk that future minor changes might break existing API consumers.
It returns rows as a list of lists of values, and expects you to correlate these with the list of columns. I originally designed it like this because I thought this was a more efficient representation than repeating the column names in a dictionary for every row. With hindsight this was a bad optimization - I _always_ use `?shape=array` because it's more convenient, and gzip encoding of the response means there's no bandwidth saving. Users who want that efficiency should request it using a custom `?_shape=`.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",627794879,
