Limit to the number of posts

  • Does anyone know with the way ID numbers are created for posts is there a limit to the number of posts a blog can have, or do they start overwriting themselves or is there some other method WP uses when say we reach 10,000 posts? Has anyone got to that number yet?

  • The post ID is the primary key in the wp_posts table. It is defined as bigint(20) unsigned, meaning that the largest value it can hold is 18,446,744,073,709,551,615. And no, no one has gotten to that number yet (even WordPress.com isn’t anywhere near)…

    Brilliant! I know WP normally scales without a problem, but I was looking at the docs and couldn’t figure out how it scaled on this occasion. Thanks for the assistance.
