Basically, I'm trying to figure out how I could allow a user to send a schedule in the cron syntax to some API, store it into the database and then send an email to them at that interval. The code is at gragorther/epigo. I'd use go-mail to send the mails.

I found stuff like River or Asynq to schedule tasks, but that is quite complex and I have absolutely no idea what the best way to implement it would be, so help with that is appreciated <3

That is accurate, though it doesn't say anything about scaling requirements

Oops, missed that part. Ideally, this would be able to handle thousands of users

Thousands is nothing, so having a single service holding the info on memory shouldn't be a problem
