Update time: July 25, 2024
GA4 recently added two new event parameters: batch_ordering_id and batch_page_id.
batch_ordering_id
batch_ordering_id: A monotonically increasing number that is incremented each time a network request is sent from a given page.
What you see in the real-time report is basically 1, and there is no different value or increase？
batch_page_id
batch_page_id：A sequential number assigned to a page that increases for each subsequent page within an engagement.
batch_page_id is the current timestamp of the sent event (13-digit timestamp), which is basically the same as the current time from the cookie named _ga_<container-id>.
For example, if I trigger an event on bbccss.com, see the name _ga_<container-id>，referral to：In-depth Understanding Session in Google Analytics 4：
The current timestamp in _ga_<container-id> is 1700107169 (10-digit timestamp), and the batch_page_id is 1700107168937 (13-digit timestamp).
current timestamp=batch_page_id/1000
