Newton Series Release Notes


New Features

  • The openstack-ansible-memcached_server role includes a new override, memcached_connections which is automatically calculated from the number of memcached connection limit plus additional 1k to configure the OS nofile limit. Without proper nofile limit configuration, memcached will crash in order to support higher parallel connection TCP/Memcache counts.

  • The memcached_server role now supports the ability to configure whether apt/yum tasks install the latest available package, or just ensure that the package is present. The default action is to ensure that the latest package is present. The action taken may be changed to only ensure that the package is present by setting memcached_package_state to present.

Upgrade Notes

  • The variable memcached_apt_packages has been renamed to memcached_distro_packages.

  • The memcached_server role always checks whether the latest package is installed when executed. If a deployer wishes to change the check to only validate the presence of the package, the option memcached_package_state should be set to present.

  • The variable verbose has been removed. Deployers should rely on the debug var to enable higher levels of memcached logging.
