333238932,MDU6SXNzdWUzMzMyMzg5MzI=,316,datasette inspect takes a very long time on large dbs,132230,closed,0,,,5,2018-06-18T11:56:27Z,2019-05-11T18:26:25Z,2019-05-11T18:26:25Z,NONE,,"Hi,

I want to expose data in a very large sqlite database (~600Gb) to the web.  I have used datasette with success on smaller test databases with the same schema - it works very well (thanks!).  However, using the full db, both `datasette inspect` and `datasette serve` seem to hang or pause for a very long time (tens of minutes) on startup.  Is this expected behaviour?

(I noticed that the output of `datasette inspect` includes row counts for each table.   Simply counting the rows in this db will take a long time (tens of millions of rows across each of ~10 tables), so I wondered if this is the source of the problem.)

Any help on a workaround would be appreciated.
