Querying costs
Please note that running queries towards BigQuery might come with a cost on your end. Currently (2024-11-22) the first 1 TiB of query data processed per month is free. See up to date pricing here.
For most users 1TiB will be enough, only users with large data volumes might be affected. Funnel will upon connect download 90 days of data and then reload the 4 most recent days of data every day.
Please keep in mind if you also use other instances to query your BigQuery data since it's a shared cost pool.
You can see your monthly BigQuery usage in the Monitoring tab here in Google Cloud console. Make sure your checking the right project and location.
Cost example
If you have ~1GiB of data per day our initial backfill will consume 90GiB of your Bytes processed for that month. After the initial backfill we will consume 3GiB per day going forward.
This means that the first month will consume ~180GiB and the following months will consume ~90GiB if you have ~1GiB of data per day going forward.
