Hello! Just wanted to chime in and note that there's a plugin to have Datasette watch for updates to an external metadata.yaml/json and update the internal settings accordingly, so I think the cache/poll use case is already covered. @khusmann If you don't need truly dynamic metadata then what you've come up with or the plugin ought to work fine.

Making the get_metadata async won't improve the situation by itself as only some of the code paths accessing metadata use that hook. The other paths use the internal metadata dict. Trying to force all paths through a async hook would have performance ramifications and making everything use the internal meta will cause problems for users that need changes to take effect immediately. This is why I came to the non-async solution as it was the path of least change within Datasette. As always, open to new ideas, etc!
