Patent number: 12222949Abstract: A method of implementing object tagging framework starts with the processor receiving a tag creation command including a tag name. In response to the tag creation command, the processor creates a current tag. The processor then receives an association command, the tag name and a source object identifier. The processor determines a source object associated with the source object identifier. The source object includes a tag value. The processor associates the current tag with the source object. The processor receives a replication command including the source object and a target object. The processor causes replication of the source object to the target object that comprises replicating the current tag with the tag name and the tag value in the source object to the target object. Other embodiments are also described herein.Type: GrantFiled: December 19, 2023Date of Patent: February 11, 2025Assignee: Snowflake Inc.Inventors: Artin Avanes, Khalid Zaman Bijon, Yujie Li, Zheng Mi, Subramanian Muralidhar, David Schultz

Patent number: 12216662Abstract: A method of implementing object tagging framework starts with the processor receiving a tag creation command including a tag name. In response to the tag creation command, the processor creates a current tag. The processor then receives an association command, the tag name and a target object identifier. The processor determines a target object associated with the target object identifier. The target object includes a tag value. The processor associates the current tag with the target object. The processor identifies a first child object of the target object. The target object and the first child object are hierarchical objects. In response to determining that the first child object is tag-unassociated, the processor associates the current tag with the first child object. In response to receiving a query including the tag name, the processor generates an output based on the tag name. Other embodiments are also described herein.Type: GrantFiled: August 9, 2023Date of Patent: February 4, 2025Assignee: Snowflake Inc.Inventors: Artin Avanes, Khalid Zaman Bijon, Yujie Li, Zheng Mi, Subramanian Muralidhar, David Schultz

Publication number: 20250013776Abstract: Row-level security (RLS) may provide fine-grained access control based on flexible, user-defined access policies to databases, tables, objects, and other data structures. A RLS policy may be an entity or object that defines rules for row access. A RLS policy may be decoupled or independent from any specific table. This allows more robust and flexible control. A RLS policy may then be attached to one or more tables. The RLS policy may include a Boolean-valued expression.Type: ApplicationFiled: September 24, 2024Publication date: January 9, 2025Inventors: Artin Avanes, Khalid Zaman Bijon, Zheng Mi, Subramanian Muralidhar, David Schultz, Jian Xu

Publication number: 20240346173Abstract: A shared database platform implements dynamic masking on data shared between users where specific data is masked, transformed, or otherwise modified based on preconfigured functions that are associated with user roles. The shared database platform can implement the masking at runtime dynamically in response to users requesting access to a database object that is associated with one or more masking policies.Type: ApplicationFiled: June 27, 2024Publication date: October 17, 2024Inventors: Artin Avanes, Khalid Zaman Bijon, Damien Carru, Thierry Cruanes, Vikas Jain, Zheng Mi, Subramanian Muralidhar

Patent number: 12120189Abstract: Embodiments of the present disclosure may provide a streamlined process for performing operations, such as data sharing and data replication, using multiple accounts. A global identity (also referred to as an organization user) may be employed, where the global identity may have access to multiple accounts across the same or different deployments. The global identity may switch between accounts from its login session and perform various tasks in the context of different accounts without undergoing further authentication.Type: GrantFiled: October 30, 2023Date of Patent: October 15, 2024Assignee: Snowflake Inc.Inventors: Khalid Zaman Bijon, Damien Carru, Christopher Peter Child, Eric Karlson, Zheng Mi

Patent number: 11971876Abstract: A database platform receives an object identifier from a client in association with a database session. The client is associated with a customer account of the database platform, and the database session is associated with the client. The customer account includes multiple disjoint account-level namespaces, each of which represents a distinct context for resolution of object identifiers, such that matching object identifiers in different account-level namespaces in the customer account do not collide with respect to object-identifier resolution. The database platform determines that the object identifier does not specify an account-level namespace, and responsively resolves the object identifier with reference to a current account-level namespace of the database session by identifying an object corresponding to the object identifier in the customer account.Type: GrantFiled: January 13, 2022Date of Patent: April 30, 2024Assignee: Snowflake Inc.Inventors: Damien Carru, Thierry Cruanes, Istvan Cseri, Benoit Dageville, Zheng Mi, Subramanian Muralidhar
