Gatsby: [gatsby-plugin-sitemap] Multiple/Split Sitemap Files

[youmustfight]

Summary

When submitting sitemaps to Google Search Console, an error is thrown for sitemaps with more than 50,000 urls. It'd be great if there was an option to have multiple sitemap files generate with a 50,000 url limit per file.

This could be done with a number limit or maybe an include option (rather than just exclude)?

Basic example

Expecting sitemap-1.xml, sitemap-2.xml, etc.

  {
    resolve: `gatsby-plugin-sitemap`,
    options: {
       split: 50000,
     }
  }

or manually defined

  {
    resolve: `gatsby-plugin-sitemap`,
    options: {
       output: `/sitemap.xml`,
       exclude: ['/learn/*'],
     }
  },
  {
    resolve: `gatsby-plugin-sitemap`,
    options: {
       output: `/sitemap-learn.xml`,
       include: ['/learn/*'],
     }
  },

Motivation

For a larger website, this is a critical way to make sure all pages are crawled and indexed!

According to this article "Google: No Technical Advantage To Splitting Up Sitemaps But Useful For Debugging" it would be nice to split the sitemap by "category" (instead of sitemapSize).

Do you guys know if it is possible to split it in this way?
