  prepare_datastore_processing_time:
    type: timing_distribution
    time_unit: microsecond
    description: >
      Measures the time taken by the parent process to prepare a datastore.
      This duration can be significantly affected by datastore preloading,
      which is triggered when a page begins to load. When a datastore is
      already preloaded, preparation is usually fast since no additional I/O
      is required. If an error occurs, the time is not recorded.
      In the future, we may introduce separate metrics to distinguish between
      different types of datastore preparations (e.g., loading data from disk
      vs. using preloaded data).

      Measures the time taken for the content process to fully set up a new

      parent process. This duration can be significantly affected by datastore
      preloading, which is triggered when a page begins loading. If an error
      occurs, the time is not recorded.
