Cloudflare K2

K2 is a durable log for decoupling event producers and consumers. Start with the K2 overview, then retrieve the relevant current documentation before giving setup instructions, code, limits, availability, permissions, or API details. The docs are the source of truth over this skill. While cloudflare-docs PR #33858 remains open, use its proposed pages if the public URLs have not been published.
