This PR introduces support for fetching a list of GCP projects via the BigQuery API. This functionality is being exposed primarily to support cross-project dataset resolution in the native BigQuery JDBC driver.

Changes included:

  • Domain Model: Added Project domain model representing a BigQuery project (@BetaApi).
  • Client Interface: Added listProjects(ProjectListOption... options) to the BigQuery client interface, marked as @InternalApi to preserve the public GA surface.
  • SPI Layer: Added listProjects mapping to BigQueryRpc and implemented the underlying HTTP execution in HttpBigQueryRpc, including pagination and OpenTelemetry tracing support.
  • Implementation: Implemented ProjectPageFetcher inside BigQueryImpl to seamlessly handle paginated project results.
  • Testing: Added unit test coverage in BigQueryImplTest and HttpBigQueryRpcTest.

This pull request introduces the ability to list Google Cloud Projects accessible to the caller. It adds a new Project model class, a ProjectListOption class for pagination options, and the listProjects method to the BigQuery interface and its implementation BigQueryImpl. It also updates the underlying RPC layer (BigQueryRpc and HttpBigQueryRpc) to support the new API call with OpenTelemetry tracing, and includes corresponding unit tests.
