Expand description

Event trait defines the interface for events that can be recorded and persisted as the system table. By default, the event will be persisted as the system table with the following schema:

type: the type of the event.
payload: the JSON bytes of the event.
timestamp: the timestamp of the event.

The event can also add the extra schema and row to the event by overriding the extra_schema and extra_row methods.
