Does firebase/GA4 data change in Bigquery retrospectively

Viewed 143

I am setting up right now GA4/Firebase in BigQuery and use dbt on top of it for analytics. Since the data of those 2 source is quite large, I want to activate incremental load and only update my analytic models for today + yesterday (instead of doing a full refresh of all the data each time).

Here is now where I am not sure: Can GA4/Firebase data change retrospectively? And if yes, how many hours/days?

Thanks in advance!

Analytics data is only sent from Firebase to BigQuery from the moment you enable the integration. No historical data from before this moment is exported.
