I understand that it must be online. However don’t you think that it would be a very good idea for the module to prevent crashing the website if suddenly redis server goes down? My redis server does not go down often but since I do not always monitor the website on a daily basis when a shared server is rebooted and cron job restarting the redis server will crash it would be wise for the module to switch itself off and alert the website admin. This would be great feature making your module more safe to use.
