问题
When I try to search for historical data for events on BigQuery I can only find events from the last week. I couldn't find anywhere the information if this is correct, or if I am doing something wrong. Basically it seems that I can only query events_YYYYMMDD from the past week. Is this correct?
回答1:
Did you by any chance enable the BigQuery export from Firebase a week ago?
Keep in mind: Firebase will only write to BigQuery that it receives from the moment you enable the integration. It won't write historical data.
