SSG - getStaticProps runs for every path immediately

[ar7casper]

Imagine I'm fetching posts from a system that has a rate limit.
Suppose I'm able to fetch 100 posts at a time and I got 300 of them.

in getStaticPathts, I'm getting the list of handles(slugs/ids) for the entire list.
Once getStaticPaths returns it's value getStaticProps runs for every post.

That results in a problem where the initial 100 posts get fetched, skipping the remaining 200.

I tried different approaches, couldn't make it work, would love to hear your ideas. Feels like there's a solution for that and I'm missing it.

Thanks.
