Scalability Testing

In an effort to test scalability of the CMS and the front end web build content has been generated to simulate a larger database.

Process to generate content

The entity_clone module was used to clone actual content to generate realistic content at scale. Content from a Section can be cloned one at a time. The logic for what content is cloned is stored within: [docroot/modules/custom/va_gov_clone/src/Plugin/VAGov/CloneHandler] folder.

To trigger a mass cloning call:

  1. Enable the va_gov_clone module via drush. This module is hidden from the admin UI so drush must be used. source /etc/sysconfig/httpd; PATH=$PATH:/usr/local/bin drush en va_gov_clone
  2. Run the drush job drush va-gov-clone:clone-all <section_tid>. For example drush va-gov-clone:clone-all 335 will clone the content for VA Ann Arbor health care section. Note that this currently only allows one section and does not pick up child sections. source /etc/sysconfig/httpd; PATH=$PATH:/usr/local/bin drush va-gov-clone:clone-all 248

Follow up tasks:

  • Allow limits to be passed in via a command line
  • Run the cloning in async.
