Event is a report of an event somewhere in the cluster. Events have a limited retention time and triggers and messages may evolve with time. Event consumers should not rely on the timing of an event with a given Reason reflecting a consistent underlying trigger, or the continued existence of events with that Reason. Events should be treated as informative, best-effort, supplemental data.
io.k8s.api.core.v1.Event is a JSON Structure definition published by Argo Workflows, describing 17 properties, of which 2 are required. It conforms to the https://json-structure.org/meta/core/v0/# meta-schema.
