717729056 MDU6SXNzdWU3MTc3MjkwNTY= 999 Datasette should default to running Uvicorn with workers=1 9599 closed 0   5971510 3 2020-10-08T23:07:03Z 2020-10-08T23:55:46Z 2020-10-08T23:21:36Z OWNER  

Uvicorn uses the WEB_CONCURRENCY variable, if set, to specify the number of workers to use.

Datasette does not work with options for this other than 1:

WEB_CONCURRENCY=2 datasette . WARNING: You must pass the application as an import string to enable 'reload' or 'workers'. This was the cause of the Heroku bug in #627.

I fixed that issue by setting WEB_CONCURRENCY=1 in datasette publish heroku, but a better fix would be to hard-code workers=1 in Datasette itself.
