Google BigQuery FAQ¶
How to allow Compose to query across projects?¶
Compose uses user account authentication. Because a Compose user authenticates using email, the email address should have access to all projects. Using IAM roles and the user’s email addresses for projects, the Compose user is provided access to query across projects.
How does a user run concurrent queries in Compose for Google BigQuery?¶
After the user account gets authenticated using the OAuth certificate, the same user can run concurrent queries on Compose for Google BigQuery as a data source. This feature is supported from Alation V R6 (5.10.x) release.
