-// Notes:
-// - All columns are NOT NULL unless specified otherwise
-// - fingerprint represents a hash of the actual data in the logical and physical expression tuple
-// - Each new event inserted into events table has its own epoch_id
-// - `cascades_group.latest_winner` is an optimization to avoid querying entire group_winner table
