 While you can track unlimited event properties with Segment, the event details page for a specific event can only show the first 300 properties. After you hit the 300 property limit, future properties are still tracked and sent to your Destinations, but they won't appear on the event details page. This limit includes nested properties in an event's `properties` object.

 **How can I clear the Schema if I have hit the limits?**
 
 If you hit any of the limits or would like to clear out old events or properties, you can clear the Schema data from your Source Settings. In your Source, navigate to Settings, then Schema Configuration. Scroll down to the **Clear Schema History** setting.

+At this time, you cannot clear or archive old event properties individually. An alternative for this is to archive the event itself, and then clear the archive. After you clear the archive, the event will re-populate in the schema with only the current properties.
