In what module is the :duct/database key defined?

What do you mean by defined?

AFAIK there's no :duct/database key, there is a :duct.database/sql though. For example the hikaricp duct init key derived from this. That way you can reference it as :duct.database/sql. If you switch to a different database pool you won't have to change this key

Thanks, @kevin.van.rooijen, but I found it in another lib being used.

Which one?

Looks like I was mistaken. It's in the code base I'm working, passed with :duct/daemon to the top-level ig/init. Not the best name for that key 😕

Ah ok, so they're starting whatever derives from :duct/database on boot I guess. A bit strange unless no other keys are referring to that key

Exactly. There are a few keys that derive from :duct/database, but no other components refer to them. Apologies, the duct ns led me to assume that it was from duct.

Crisis averted 👍
