Snowflake data policy impersonation

Image #1

Snowflake data policy impersonation is enabled for all accounts. Impersonation is now compatible with the latest version of Immuta’s Snowflake integration, which uses low-row access policy mode for improved overall performance.

With this update,

  • Impersonation is available for data policy access only.

  • Administrators can impersonate users to view the row- and column-level restrictions applied to them.

  • The impersonator’s subscription policy access remains unchanged while impersonating another user.

🗓  This release follows Immuta’s standard behavior change release process. The specific dates for each phase in that process are outlined below.

  • Opt-in period: January 22 – February 22

  • On by default period: February 23 – March 22

  • Enabled for all accounts: March 23
