How long before Rhythmbox on Ubuntu detects a newly added MusicBrainz CD entry?

I just uploaded Joao’s album here and it’s not detected by Rhythmbox. I’m using Ubuntu and I typically rely on Rhythmbox as my go-to for ripping CDs and auto-pulling CD metadata from the internet (in this case MusicBrainz).

Thank you.

Looks like–to answer my own question–less than two hours! But perhaps it can vary.
