For metadata crawling (required)

To configure permissions for crawling metadata, add the following permissions to the role:

  • bigquery.datasets.get allows Atlan to retrieve metadata about a data set.
  • bigquery.datasets.getIamPolicy allows Atlan to read a data set's IAM permissions.
  • bigquery.jobs.create allows Atlan to run jobs (including queries) within the project.
    🚨 Careful! Without this, Atlan can't query the source.
  • bigquery.routines.get allows Atlan to retrieve routine definitions and metadata.
  • bigquery.routines.list allows Atlan to list routines and metadata on routines.
  • bigquery.tables.get allows Atlan to retrieve table metadata.
  • bigquery.tables.getIamPolicy allows Atlan to read a table's IAM policy.
  • bigquery.tables.list allows Atlan to list tables and metadata on tables.
  • bigquery.readsessions.create allows Atlan to create a session to stream large results.
  • bigquery.readsessions.getData allows Atlan to retrieve data from the session.
  • bigquery.readsessions.update allows Atlan to cancel the session.
  • resourcemanager.projects.get allows Atlan to retrieve project names and metadata.

To add data preview and querying (optional)

To configure permissions for previewing and querying data, add the following permissions to the role:

  • bigquery.tables.getData allows Atlan to retrieve table data.
    🚨 Careful! This permission is also required for retrieving metadata such as the row count and update time of a table.
  • bigquery.jobs.get allows Atlan to retrieve data and metadata on any job, including queries.
  • bigquery.jobs.listAll allows Atlan to list all jobs and retrieve metadata on any job submitted by any user.
  • bigquery.jobs.update allows Atlan to cancel any job, including a running query.

To add query history mining (optional)

To configure permissions for mining query history, add the following permissions to the role:
