I recently upgraded Bigquery from sandbox mode and would like to remove data set expiration date. Could anybody share which setting I should change after the upgrade and how to
In order to change the retention settings you have to change it from Google Analytics rather than inside BigQuery:
Admin
which is in the bottom of the homepageData Settings
and then on Data Retention
Event data retention
from 2 months to 14 months which is the longest retention period and click on Save
Now you can go back to the Firebase Console and you will notice that the "Data to live" has change.
