Notification Process

If we enable notification over a folder so that user receives an email if a new item is added inside it, the process which content server follows from item addition to sending user an email follows the following steps:

1. When an item is added, an event is generated which gets stored in NotifyEvents table.
2. Agent 8999 processes these events from NotifyEvents to LLEventQueue and then deletes entry from NotifyEvents table.
3. Agent 9000 processes requests from LLEventQueue and writes it down to NotifyMessages after checking user’s notification settings.
4. Agent 9999 sends email for every entry in NotifyMessages table to SMTP server. After 9999 has finished processing, agent 4000 deletes entries in NotifyMessages table.
5. Two threads enables agent to execute- Notify102, to handle all notification related agents and Agent101 to handle all other agents.
