google-bigquery

问题 I am trying to build up a matrix out of a table that is imported from Google Analytics data into BigQuery. The table represents hits on a website that contain session_IDs alongside some properties such as the url, timestamp etc. Also, there are some metadata based on user-defined actions that we refer to as events. Below is an example of the table. session_id hit_timestamp url event_category 1 11:12:23 url134 event1 1 11:14:23 url2234 event2 1 11:16:23 url_target null 2 03:12:11 url2344

问题 Trying to create a bigquery connector using sqlalchemy from sqlalchemy import create_engine engine = create_engine('bigquery://<project_id>/<project_name>', credentials_path=GCP_KEY) conn = engine.connect() Error: sqlalchemy.exc.NoSuchModuleError: Can't load plugin: sqlalchemy.dialects:bigquery 回答1: Your error is generally related to the lack of some required module to use SQLAlchemy.

问题 I have enabled the BigQuery integration in Firebase Console and I have some issues about this : How long will Firebase Analytics Data be exported to BigQuery ? I had the integration from Firebase to BigQuery, somehow Firebase Analytics Data export was disabled by somebody. I just enabled it yesterday around 17:00, and there is no data updated in BigQuery so far. Why Firebase Analytics Data will be updated even thought the data is moved from intraday data set to event data set ? I find the

问题 I have created a table from Google Cloud Storage (filepath starts with gs://). I could not create it as native even after trying multiple times. I succeeded only after setting the table option as native. Later, I was able to query this table successfully. However, I need to do the following: Add a column to the table Append (union) two such external tables Join the appended table with another external table save the joined table in a new table so that I can later query this new table
