Thanks for sharing Taylor.

I took a quick look at the code and it seems that 10up sitemaps cache all urls in the options table correct? I am curious to hear how it performs with X million posts.

In the current version of the MVP featured plugin, we only rely on cron to get the lastmod date for index sitemap urls which links to all object sitemaps (should remain a small list even for very large sites).

I would love for you guys to contribute to the project and continue these discussions in the upcoming WordPress dedicated slack channel which should kick start in ~ 2 weeks,
