Streaming and Updates
BigQuery streaming export makes data for the current day available within a few minutes via BigQuery Export.
You can choose the streaming export option when linking your Google Analytics 4 property to BigQuery. This option is best for real-time data analysis and is a best-effort service, meaning it may not include all data due to processing delays or failed uploads.
Streaming export creates two tables: events_intraday_YYYYMMDD: An internal staging table that includes records of session activity.events_YYYYMMDD: The full daily export of events. You should query the events_YYYYMMDD table for a stable dataset.
BigQuery streaming export does not include user-attribution data for new users, which may be delayed by up to 24 hours. You will incur additional BigQuery costs for using streaming export at the rate of $0.05 per gigabyte of data.
Streaming Export
Streaming export is a great option for getting near real-time data from Google Analytics. You can choose this option when linking your Google Analytics 4 property to BigQuery.
BigQuery streaming export makes data for the current day available within a few minutes via BigQuery Export. This can be super helpful for analyzing user behavior and traffic on your property.
Streaming export creates two tables for each day: events_intraday_YYYYMMDD and events_YYYYMMDD. However, you should query events_YYYYMMDD instead of events_intraday_YYYYMMDD for a stable dataset.
Streaming export does not include user-attribution data for new users, specifically traffic_source.name, traffic_source.source, and traffic_source.medium. This means you won't get the full picture of how users are interacting with your property.
You'll incur additional BigQuery costs for using streaming export at the rate of $0.05 per gigabyte of data. This works out to approximately 600,000 Google Analytics events per gigabyte, although this number can vary depending on event size.
Here's a summary of the streaming export options:
Keep in mind that updates to the tables created as part of BigQuery Export are governed by the time zone of the Analytics property from which data is being exported. This means that changing the property time zone can impact the BigQuery export and lead to data discrepancies.
Table Update Schedule

Streaming-export tables, like events_intraday_YYYYMMDD, are updated continuously throughout the day in the property's time zone.
This means they get updated from 12:00:00 am until 11:59:59 pm, so you can expect a fresh update every day.
Daily export tables, like events_YYYYMMDD, are created after Analytics collects all the events for the day.
They're then updated for up to 72 hours beyond the table's date with events that match the table's date, like event bundles that come in late.
For example, if the table date is 20220101, Analytics will update the table through 20220104 with events that are timestamped 20220101.

GA4 and Firebase
GA4 and Firebase can be integrated, but there's a catch. If you link them, you can't use separate BigQuery projects.
This integration can be useful for streamlined data analysis, but it's essential to consider the implications for your data storage and management.
In this scenario, you'll need to manage your BigQuery projects accordingly to avoid any potential issues.
Device Summary

The device_summary table is a powerful tool in GA4 and Firebase, containing aggregated statistics by month, origin, country, and device. It's like having a snapshot of your app's performance at a glance.
This table includes all the metrics you'd find in the metrics_summary columns, plus some extra goodies like aggregated statistics.
The device_summary table is a treasure trove of information, and you can use it to track how different devices are performing across various metrics.
Ga4 - Firebase Integration
GA4 - Firebase Integration is a powerful combination that can help you get the most out of your analytics and app development tools. If you integrate a GA4 property and a Firebase project, they cannot be linked to separate BigQuery projects. This means you'll need to set up a single BigQuery project that serves both your GA4 and Firebase data.
