Snowflake says its Horizon Catalog now extends row access and masking policies to external engines including Apache Spark, Trino and PyIceberg in public preview. The change lets those engines receive only the data a user is authorized to see when Horizon plans a data scan. Operations are recorded in Snowflake's access history. The company also describes agent identities that let administrators set data permissions independently from the invoking user and attribute actions to both. The external-engine policy extension remains in public preview.
