+	 * or 'failed' or 'trash', WordPress will find a unique slug (stored in post_name column) using the wp_unique_post_slug()

+	 * post_name values that match, and append a number 1 greater than the largest. This makes sense when manually creating a
+	 * post from the Edit Post screen. It becomes a bottleneck when automatically processing thousands of actions, with a
+	 * database containing thousands of related post_name values.
+	 *
+	 * WordPress 5.1 introduces the 'pre_wp_unique_post_slug' filter for plugins to address this issue.
+	 *
+	 * We can short-circuit WordPress's wp_unique_post_slug() approach using the 'pre_wp_unique_post_slug' filter. This
+	 * method is available to be used as a callback on that filter. It provides a more scalable approach to generating a
+	 * post_name/slug that is probably unique. Because Action Scheduler never actually uses the post_name field, or an
+	 * action's slug, being probably unique is good enough.
+	 *
