Hi devs ! Currently working on [XWIKI-14353](https://jira.xwiki.org/browse/XWIKI-14353), I think that the live e-mail notification system could be implement as 2 different ways :
1. In its notification preferences, a user can select if he wants a mail daily, hourly or weekly (that’s already in place). We could add a new "live" option that does exactly what is expected : it sends a mail as soon as a document has been updated. 2. We could also provide a completely different option that sends live e-mails, but regular notification mails are still sent depending on the user preference and acts as a hourly / daily or weekly "digest". Finally one idea would be to use the same system that is implemented in discourse : a mail is sent approximately 10 minutes after an event is triggered, this means that if a user A is subscribed to the events coming form a document X, if this document is updated by someone else, the updates coming from the document in the next 10 minutes will be grouped in a single mail that will be sent to A. This could potentially be more scalable as less mails are sent to the users. WDYT ? Thanks, -- Clément Aubin Web Developer Intern @XWiki SAS [email protected] More about us at http://www.xwiki.com
