Zero-Copy Sharing with Analytics Hub Listings

What Analytics Hub is:

Analytics Hub is a fully managed data exchange service built on top of BigQuery that allows organizations to securely discover, share, and govern datasets at scale across organizational and project boundaries.

How it meets the requirements:

• Zero-copy architecture (✓): Analytics Hub enables data publishers to create listings backed by BigQuery datasets. Subscribers create a read-only linked dataset in their own BigQuery projects, allowing them to query the data in place without copying or duplicating underlying storage.
• Centralized governance and monitoring (✓): Publishers manage access through private or public exchanges, monitor subscribers, view telemetry on dataset usage, and revoke access instantly when contracts expire.
• Separation of storage and compute billing (✓): Subscribers pay for their own query compute slots/on-demand processing within their own GCP billing accounts, while the publisher only pays for their primary dataset storage without incurring cross-project egress fees.

Key advantages and capabilities:

• Linked Datasets: Subscribers access live, up-to-date data immediately without needing scheduled export pipelines or ETL jobs.
• Granular Access Control: Exchange administrators can restrict listings to specific external organizations, Google Groups, or IAM identities.
• Data Clean Rooms: Supports privacy-preserving collaborative queries without exposing underlying raw or sensitive personal data.
• Auditability and Metrics: Integration with Cloud Audit Logs and BigQuery administration tools provides visibility into listing subscriptions.

Why this is optimal:

Analytics Hub is purpose-built for multi-organization data sharing and data democratization. It eliminates the maintenance burden, synchronization latency, and storage replication costs associated with traditional file-based exports or direct table replication.
