You want to provide third-party companies access to a BigQuery dataset, keep sharing costs low, and ensure data stays current. Which solution should you choose?

Analytics Hub is designed for secure, real-time data sharing with external parties. It allows you to publish BigQuery datasets as listings, providing subscribers with direct, read-only access to the underlying data without creating copies. This keeps sharing costs low as subscribers pay for their own queries, and ensures data is always current since they access the live dataset. Exporting to Cloud Storage or creating a separate dataset would incur storage costs for the shared data and require manual synchronization to keep it current. A Dataflow job would add complexity, operational overhead, and additional processing costs.
