This module implements Openstack Zaqar as a queue backend for Drupal. Zaqar is designed as an alternative to other cloud queuing systems such as Amazon SQS and is known to be currently used in production at Rackspace.

This is an enhancement over drupal's default cache.

This module lets you craft and expose a GraphQL schema for Drupal 8.

It is is built around https://github.com/Youshido/GraphQL. As such, it supports the full official GraphQL specification with all its features.

You can use this module as a foundation for building your own schema through custom code or you can use and extend the generated schema using the plugin architecture of the contained sub-modules.

This module extends the api capabilities of ctools content types provided by the Chaos tool suite. It allow a developer to hard code cache settings in their ctools content types, to avoid making site builders having to configure cache manually.

I'd like to see this functionality go into panel core, and have opened a ticket with the maintainers.

What?

Saves live front-end timing numbers back into the db with uncacheable AJAX via custom entry script with super simple bootstrap for super speeds.

What??

Any user visits the site (any page, any role etc), when the page is definitely done loading a JS sends 2 numbers back to live_timing.php: domready time and onload time. Both come from performance.timing, so only decent browsers are supported.

INTRODUCTION

XML sitemap Http Cache (XHC).

This module uses non blocking batch job requests for generating http cache pages for Nginx fastcgi and such, from sitemap.xml files provided by the xmlsitemap module.
The method used for cache generation is PHP's Curl "fresh connect" requests.

You will also get the optional xhc_cron module, for planning daily http cache warmup with cron tasks for Drupal's awesome Elysia cron module.
