* Right now Datasette assumes it can always show the count of rows in a table, because this has been pre-calculated. If a database is mutable the pre-calculation trick no longer works, and for giant tables a `select count(*) from X` query can be expensive to run. Maybe we set a time limit on these? If time limit expires show ""many rows""?
* Maintaining a content hash of the table no longer makes sense if it is changing (though interestingly there's a `.sha3sum` built-in SQLite CLI command which takes a hash of the content and stays the same even through vacuum runs). Without that we need a different mechanism for calculating table colours. It also means that we can't do the special dbname-hash URL trick (see #418) at all if the database is opened as mutable.","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",421551434,
