I implemented the follow system exactly as @hubertlepicki suggested. Now I’m struggling how to notify the followers when the followee takes some action (e.g. posts a new article). I tried to insert notifications, one for each follower, into database in a separate process (using Task.start), but my test always shows me that the db connection has been closed by the parent process. How can I make the test process wait for those tasks to finish?

Entirely plausible, depends on the rest of the schema, I make indexes on compound fields all the time.
