Performance impact

  • Adds an extra column to xf_alert.

    Code:


  • alter table xf_user_alert summerize_id add int(10) unsigned DEFAULT NULL
  • 1 extra SELECT query per thread page request when the user has more than zero active alerts.
    • If there are alerts to mark as read, then an extra UPDATE is required.
Alert Summerization Performance impact

  • On accessing alerts above the summerize threshold, fetches all unread alerts and attempts to group them in PHP.
  • On successfully generating summary alerts, 2 queries are done. 1 insert to add the summary alert, 1 updating summerized alerts.
