A Data Exchan…Data Exchange in Snowflake is a powerful feature that enables organizations to securely share and consume data with external parties, creating a collaborative data ecosystem. It serves as a hub where data providers can publish datasets and data consumers can discover and access them.
A Data Exchange functions as a private marketplace for data sharing between selected participants. Unlike public marketplaces, Data Exchanges are invitation-only environments where organizations control who can participate. This makes them ideal for sharing sensitive information between business partners, subsidiaries, or trusted third parties.
Key characteristics of Data Exchange include:
1. **Governance and Control**: Data providers maintain complete control over their shared data. They can define access policies, track usage, and revoke access at any time. The original data never leaves the provider's account, ensuring data sovereignty.
2. **Live Data Access**: Consumers access real-time data rather than static copies. This eliminates data staleness and reduces storage costs since no physical data movement occurs between accounts.
3. **Secure Sharing**: All data sharing happens within Snowflake's secure infrastructure. Data is encrypted and protected by role-based access controls, ensuring compliance with security requirements.
4. **Listings**: Providers create listings that describe available datasets, including metadata, sample data, and usage terms. Consumers browse these listings to find relevant data for their needs.
5. **Cross-Region and Cross-Cloud Sharing**: Data Exchanges support sharing across different Snowflake regions and cloud platforms, enabling global data collaboration.
6. **Reader Accounts**: Providers can create reader accounts for consumers who do not have their own Snowflake accounts, expanding the potential audience for shared data.
Data Exchange differs from Snowflake Marketplace, which is a public platform open to all Snowflake customers. Organizations use Data Exchanges for controlled, private data sharing scenarios where participant selection and data governance are paramount priorities.

What is Data Exchange?
Data Exchange is a Snowflake feature that enables organizations to create a private, curated marketplace for sharing data among a defined group of participants. Unlike the public Snowflake Marketplace, Data Exchanges are private hubs where providers and consumers within a trusted network can discover, request, and share data securely.
Why is Data Exchange Important?
Data Exchange addresses several critical business needs:
1. Controlled Data Sharing: Organizations can share data with specific partners, subsidiaries, or departments while maintaining strict governance over who can access what data.
2. Centralized Discovery: Participants can browse available datasets in one location, making it easier to find and access relevant data assets.
3. Elimination of Data Movement: Like other Snowflake sharing features, Data Exchange allows consumers to access live data from the provider's account, ensuring data is always current and reducing storage costs.
4. Business-to-Business Collaboration: Enables secure data collaboration between organizations, suppliers, customers, and partners.
How Data Exchange Works
Key Components: - Exchange Admin: The organization that creates and manages the Data Exchange, controlling membership and access policies. - Providers: Members who publish listings (data products) to the exchange. - Consumers: Members who discover and request access to listings. - Listings: Data products published by providers, which can include databases, schemas, or specific objects.
Process Flow: 1. An organization requests a Data Exchange from Snowflake 2. The Exchange Admin invites members to join the exchange 3. Providers create and publish listings containing their shared data 4. Consumers browse listings and request access 5. Providers approve or deny access requests 6. Once approved, consumers can query the shared data
Types of Listings: - Free Listings: Data shared at no cost - Personalized Listings: Customized data offerings for specific consumers - Paid Listings: Commercial data products with associated costs
Key Features
- Data remains in the provider's account (no copying) - Real-time access to current data - Role-based access control for governance - Support for cross-region and cross-cloud sharing through replication - Audit trails for compliance and monitoring
Exam Tips: Answering Questions on Data Exchange
Focus Areas for the Exam:
1. Understand the difference between Data Exchange and Marketplace: Data Exchange is private and invitation-only, while Marketplace is public. This distinction appears frequently in exam questions.
2. Know the roles: Be clear about Exchange Admin, Provider, and Consumer responsibilities. Questions may ask about who can perform specific actions.
3. Remember data location: Data stays with the provider - consumers query it from the provider's account. No data copying occurs.
4. Listing types: Understand that listings can be free, personalized, or paid.
5. Cross-region sharing: Data Exchange can work across regions and clouds when combined with replication features.
Common Question Patterns:
- Questions comparing secure data sharing, Data Exchange, and Marketplace - Scenarios asking which solution fits a specific use case (private vs public sharing) - Questions about who manages membership in a Data Exchange - Cost and billing-related questions (consumer uses their own compute)
Key Points to Remember:
- Only Snowflake can provision a new Data Exchange upon request - Exchange Admins control who can join and what roles members have - Consumers use their own compute resources to query shared data - Providers maintain full control over their data and can revoke access at any time - Data Exchange supports both same-region and cross-region sharing scenarios
