How can I optimize the cost-efficiency of dynamic table refreshes?

Sharing dynamic tables with other Snowflake accounts unlocks collaboration and data exchange possibilities. However, there are some key considerations to keep in mind:

Sharing Mechanism:

  • Direct Sharing: You can directly share specific dynamic tables and underlying objects (like the schema) with another Snowflake account within the same region. This grants them read access to the materialized results of the dynamic table.
  • Listings (Preview): This option allows you (the provider) to create a curated list of data assets, including dynamic tables, and offer them to other accounts. Recipients can subscribe to the listing and gain access to the shared data objects.

Data Security:

  • Access Control: Even with sharing enabled, you can define granular access control for the recipient account. This determines what level of access they have (e.g., read-only) to the shared dynamic table.
  • Data Lineage: Sharing dynamic tables doesn't automatically share the underlying source data. Ensure the recipient account has access to the source data itself or the results might be incomplete.

Dynamic Table Considerations:

  • Refresh Schedules: The refresh schedule of the dynamic table remains under your control (the provider). However, consider how changes in the schedule might impact the recipient's access to up-to-date data.
  • Dependencies: If your dynamic table relies on other tables, ensure the recipient has access to all dependencies within your account or theirs for successful data access.
  • Target Lag: Be mindful of the target lag (desired refresh frequency) for the dynamic table. The recipient might experience delays if the lag time is high.

Additional Considerations:

  • Data Governance: Establish clear data governance policies around shared dynamic tables, including usage guidelines and data ownership definitions.
  • Monitoring and Auditing: Monitor how the shared dynamic table is being used by the recipient account. Utilize Snowflake's auditing features to track access patterns and identify any potential security concerns.

By carefully considering these factors, you can leverage the power of Snowflake's dynamic table sharing to enable secure and efficient data collaboration between accounts.
