Templates for long running events, like General Admission, may end up accruing a number of schedules. At some point, having a lot schedules on an event can slow down the event performance, which can impact publish times, API call responsiveness, and generally cause latency issues.
Any schedules where both the start and end dates are in the past can be deleted.
- Edit the Template, and navigate to the Schedules tab.
- Open any schedule where both the start and end dates are in the past.
- Click Delete.
- Repeat as needed before saving and publishing the template.
Outcome: This will cause all past instances created by this schedule to become unlinked, but they will all remain on the events lists for the prior days as originally scheduled, even if no tickets were sold for that event instance.
