Defined in:
lib/webhookdb/replicator/icalendar_event_v1.rb

Overview

Delete CANCELLED events last updated (row_updated_at)‘ in the window between stale_at to age_cutoff. This avoids endlessly adding to the icalendar events table due to feeds that change UIDs each fetch- events with changed UIDs will become CANCELLED, and then deleted over time.
