-- This file specifies common metrics/tables for critical user interactions. It

-- Currently we only track Chrome page loads and their associated metrics.

INCLUDE PERFETTO MODULE chrome.page_loads;

-- All critical user interaction events, including type and table with
-- associated metrics.
CREATE PERFETTO TABLE chrome_interactions(
  -- Identifier of the interaction; this is not guaranteed to be unique to the table -
  -- rather, it is unique within an individual interaction type. Combine with type to get
  -- a unique identifier in this table.
  scoped_id INT,
  -- Type of this interaction, which together with scoped_id uniquely identifies this
  -- interaction. Also corresponds to a SQL table name containing more details specific
  -- to this type of interaction.
  type STRING,
  -- Interaction name - e.g. 'PageLoad', 'Tap', etc. Interactions will have unique metrics
  -- stored in other tables.
  name STRING,
  -- Timestamp of the CUI event.
  ts INT,
  -- Duration of the CUI event.
