Support limitation: This policy is only supported in Snowflake integrations.
Sample data is processed during computation of randomized response policies
When a randomized response policy is applied to a data source, the columns targeted by the policy are queried under a fingerprinting process. To enforce the policy, Immuta generates and stores predicates and a list of allowed replacement values that may contain data that is subject to regulatory constraints (such as GDPR or HIPAA) in Immuta's metadata database.
The location of the metadata database depends on your deployment:
Self-managed Immuta deployment: The metadata database is located in the server where you have your external metadata database deployed.
SaaS Immuta deployment: The metadata database is located in the AWS global segment you have chosen to deploy Immuta.
