The expanded table represents Caliper tables in a wide table of diverse columns and structures. By exploding JSON-source Caliper events into a wide tabular structure, the expanded table offers a performant, scalable method of accessing terabytes of event data at low-cost.
The events table is a legacy BigQuery table that captures all event data for all time. Its schema provides complete, but basic, access to Caliper events captured by the UDP. This table has been deprecated and is no longer in use.
