is events_yyyymmdd created at once?

[AElashry]

Talking about the data export from GA4 to BigQuery, in logs explorer I see an InsertJob for the events_yyyymmdd table and after 15-20 minutes a DeleteTable for the events_intraday_yyyymmdd.

Is there any reason for that?

If I am creating a pipeline to process this data once it's complete is it safe to work on the creation of the events_yyyymmdd table or the deletion of the events_intraday_yyyymmdd?

Thank you in advance!
