Such an fts table can be created using sqlite_utils, where one created with your method can't.

I can see the argument for removing this and just using an array for convenience - but I think that's OK as an option (as you have now). Rather than have lots of top-level keys you could have a ""meta"" object to contain non-data stuff. You could use something like ""links"" for API endpoint URLs (or use a standard like HAL).

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. So I think this is OK.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",627794879, https://github.com/simonw/datasette/issues/782#issuecomment-782741107,https://api.github.com/repos/simonw/datasette/issues/782,782741107,MDEyOklzc3VlQ29tbWVudDc4Mjc0MTEwNw==,9599,2021-02-20T20:00:22Z,2021-02-20T20:00:22Z,OWNER,"A really exciting opportunity this opens up is for parallel execution - the `facets()` and `suggested_facets()` and `total()` async functions could be called in parallel, which could speed things up if I'm confident the SQLite thread pool can execute on multiple CPU cores (it should be able to because the Python `sqlite3` module releases the GIL while it's executing C code).","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",627794879, https://github.com/simonw/datasette/issues/782#issuecomment-782740985,https://api.github.com/repos/simonw/datasette/issues/782,782740985,MDEyOklzc3VlQ29tbWVudDc4Mjc0MDk4NQ==,9599,2021-02-20T19:59:21Z,2021-02-20T19:59:21Z,OWNER,"This design should be influenced by how it's implemented. 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.

It's the simplest-thing-that-could-possibly-work: you can run `datasette one.db two.db three.db --crossdb` and then use the `/_memory` page to run joins across tables from multiple databases. It only works on the first 10 databases that were passed to the command-line. This means that if you have a Datasette instance with hundreds of attached databases (see [Datasette Library](https://github.com/simonw/datasette/issues/417)) this won't be particularly useful for you. So... a better, future version of this feature would be one that lets you join across databases on command - maybe by hitting `/_memory?attach=db1&attach=db2` to get a special connection. Also worth noting: plugins that implement the [prepare_connection()](https://docs.datasette.io/en/stable/plugin_hooks.html#prepare-connection-conn-database-datasette) hook can attach additional databases - so if you need better, customized support for this one way to handle that would be with a custom plugin.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",325958506, https://github.com/simonw/datasette/pull/1232#issuecomment-781651283,https://api.github.com/repos/simonw/datasette/issues/1232,781651283,MDEyOklzc3VlQ29tbWVudDc4MTY1MTI4Mw==,9599,2021-02-18T21:37:55Z,2021-02-18T21:37:55Z,OWNER,"UI listing the attached tables: ","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",811407131, https://github.com/simonw/datasette/pull/1232#issuecomment-781641728,https://api.github.com/repos/simonw/datasette/issues/1232,781641728,MDEyOklzc3VlQ29tbWVudDc4MTY0MTcyOA==,9599,2021-02-18T21:19:34Z,2021-02-18T21:19:34Z,OWNER,"I tested the demo deployment like this: ``` datasette publish cloudrun fixtures.db extra_database.db \ -m fixtures.json \ --plugins-dir=plugins \ --branch=crossdb \ --extra-options=""--setting template_debug 1 --crossdb"" \ --install=pysqlite3-binary \ --service=datasette-latest-crossdb ```","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",811407131, https://github.com/simonw/datasette/pull/1232#issuecomment-781637292,https://api.github.com/repos/simonw/datasette/issues/1232,781637292,MDEyOklzc3VlQ29tbWVudDc4MTYzNzI5Mg==,9599,2021-02-18T21:11:31Z,2021-02-18T21:11:31Z,OWNER,Due to bug #1233 I'm going to publish the additional database as `extra_database.db` rather than `extra database.db` as it is used in the tests.,"{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",811407131, https://github.com/simonw/datasette/issues/1233#issuecomment-781636590,https://api.github.com/repos/simonw/datasette/issues/1233,781636590,MDEyOklzc3VlQ29tbWVudDc4MTYzNjU5MA==,9599,2021-02-18T21:10:08Z,2021-02-18T21:10:08Z,OWNER,I think the bug is here: https://github.com/simonw/datasette/blob/640ac7071b73111ba4423812cd683756e0e1936b/datasette/utils/__init__.py#L349-L373,"{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",811458446, https://github.com/simonw/datasette/pull/1232#issuecomment-781634819,https://api.github.com/repos/simonw/datasette/issues/1232,781634819,MDEyOklzc3VlQ29tbWVudDc4MTYzNDgxOQ==,9599,2021-02-18T21:06:43Z,2021-02-18T21:06:43Z,OWNER,I'll document this option on https://docs.datasette.io/en/stable/sql_queries.html,"{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",811407131, https://github.com/simonw/datasette/pull/1232#issuecomment-781629841,https://api.github.com/repos/simonw/datasette/issues/1232,781629841,MDEyOklzc3VlQ29tbWVudDc4MTYyOTg0MQ==,9599,2021-02-18T20:57:23Z,2021-02-18T20:57:23Z,OWNER,"The new warning looks like this: ","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",811407131, https://github.com/simonw/datasette/pull/1232#issuecomment-781599929,https://api.github.com/repos/simonw/datasette/issues/1232,781599929,MDEyOklzc3VlQ29tbWVudDc4MTU5OTkyOQ==,22429695,2021-02-18T19:59:54Z,2021-02-18T22:06:42Z,NONE,"# [Codecov](https://codecov.io/gh/simonw/datasette/pull/1232?src=pr&el=h1) Report > Merging [#1232](https://codecov.io/gh/simonw/datasette/pull/1232?src=pr&el=desc) (8876499) into [main](https://codecov.io/gh/simonw/datasette/commit/4df548e7668b5b21d64a267964951e67894f4712?el=desc) (4df548e) will **increase** coverage by `0.03%`. > The diff coverage is `100.00%`.
