For example: - I put a new CSV file into the import dir and a new table is created therefrom - I put a CSV file into the import dir that replaces a previous file / table of the same name as a pre-existing table (eg files that contain monthly data in year to date). The data may also patch previous months, so a full replace / DROP on the original table may well be in order. - I put a CSV file into the import dir that updates a table of the same name as a pre-existing table (eg files that contain last month's data) CSV files may also have messy names compared to the table you want.

I'm going to try and implement this is a core Datasette feature (no plugins) with the following design: - You can tell Datasette ""load any databases you find in this directory"" by passing the `--dir=path/to/dir` option to `datasette` that are valid SQLite files and will attach them to Datasette - Every 10 seconds Datasette will re-scan those directories to see if any new files have been added - That 10s will be the default for a new `--config directory_scan_s:10` config option. You can set this to `0` to disable scanning entirely, at which point Datasette will only run the scan once on startup. To check if a file is valid SQLite, Datasette will first check if the first few bytes of the file are `b""SQLite format 3\x00""`. If they are, it will open a connection to the file and attempt to run `select * from sqlite_master` against it. If that runs without any errors it will assume the file is usable and connect it.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",421546944, https://github.com/simonw/datasette/issues/417#issuecomment-586047995,https://api.github.com/repos/simonw/datasette/issues/417,586047995,MDEyOklzc3VlQ29tbWVudDU4NjA0Nzk5NQ==,9599,2020-02-14T01:05:20Z,2020-02-14T01:05:20Z,OWNER,"I'm going to add two methods to the Datasette class to help support this work (and to enable exciting new plugin opportunities in the future): - `datasette.add_database(name, db)` - adds a new named database to the list of connected databases. `db` will be a `Database()` object, which may prove useful in the future for things like #670 and could also allow some plugins to provide in-memory SQLite databases. - `datasette.remove_database(name)`","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",421546944, https://github.com/simonw/datasette/issues/417#issuecomment-586065843,https://api.github.com/repos/simonw/datasette/issues/417,586065843,MDEyOklzc3VlQ29tbWVudDU4NjA2NTg0Mw==,9599,2020-02-14T02:20:53Z,2020-02-14T02:20:53Z,OWNER,"MVP for this feature: just do it once on startup, don't scan for new files every X seconds.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",421546944, https://github.com/simonw/datasette/issues/417#issuecomment-586066798,https://api.github.com/repos/simonw/datasette/issues/417,586066798,MDEyOklzc3VlQ29tbWVudDU4NjA2Njc5OA==,9599,2020-02-14T02:24:54Z,2020-02-14T02:24:54Z,OWNER,I'm going to move this over to a draft pull request.,"{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",421546944, https://github.com/simonw/datasette/issues/417#issuecomment-586599424,https://api.github.com/repos/simonw/datasette/issues/417,586599424,MDEyOklzc3VlQ29tbWVudDU4NjU5OTQyNA==,82988,2020-02-15T15:12:19Z,2020-02-15T15:12:33Z,CONTRIBUTOR,So could the polling support also allow you to call sqlite_utils to update a database with csv files?
