Best way to bulk import 200,000+ users

Hi,

I’m trying to work out what is the best way to bulk load our 200,000+ users.
I started reading this

Looks like there are two limitations I can see

  • that 500kb limit
  • that only being able to queue up to 2 jobs at a time

These make it look like there is a bunch of extra development we need to do to load our users with things like polling for jobs that complete, submit new ones etc.

It is not clear to me whether the import/export extension can help with this or indeed what benefit it provides? Can we give it all our users and will it take care of submitting and polling jobs?

So in summary, my questions are:
Q1) What benefit does the extension provide and should we use that?
Q2) Are there any tools/projects available that would take care of this one-time activity?

Cheers
Oliver
