I have linked Bigquery to my app through Firebase and it has worked well for more than 3 months. However, couple days ago, a random dataset called "analytics_156951304" was created and then the app data was streamed into this dataset instead of the original dataset that Bigquery created for me when I first linked my app to Bigquery, "my_app_name_IOS". And the table schema was changed too. I checked Stackdriver logging and it said an account called "[email protected]" created this job at midnight of my local time. However, I have no clue what happened and how to get my streaming data back to my original dataset, "my_app_name_IOS". Thank you for all the answers!!!

Firebase recently scheduled a huge schema migration - your previous queries won't work anymore.
(AFAIK this was communicated via email)
There's a script that helps migrating your previous datasets to the new schema:
(tho the script won't help with modifying the existing queries)
From the email I got:
Currently, the data from each app in a Firebase project are exported to a distinct BigQuery dataset in the corresponding BigQuery project. Going forward, the data from each app in a Firebase project will be exported to a single dataset in that BigQuery project. Additionally, the data in this new dataset will follow a new schema.
