You can now create an external dataset in BigQuery that links to an existing database in Spanner

## Feature You can now create an [external dataset](https://cloud.google.com/bigquery/docs/spanner-external-datasets) in BigQuery that links to an existing database in [Spanner](https://cloud.google.com/spanner/docs/). This feature is in [preview](https://cloud.google.com/products/#product-launch-stages). ## Feature [ODBC driver update, release 3.0.7 1016](https://cloud.google.com/bigquery/docs/reference/odbc-jdbc-drivers#current%5Fodbc%5Fdriver) * \[New\] Connector authentication on Google Cloud VMs: The connector now supports authentication through Application Default Credentials using the Google internal metadata server, eliminating the need for a keyfile. This feature works only on Google Cloud Compute Engine VMs. * \[Resolved\] The output for PrimaryKeys previously denoted the Key Sequence as a 0-indexed value. This has been corrected to a 1-indexed value, indicating the sequential order of the primary key's column within the primary key itself.
