Patent number: 11928108Abstract: Aspects of the present disclosure address systems, methods, and devices for tracking object dependencies in a cloud database system. An object dependency created between a referencing object and a referenced object is detected. Based on detecting the object dependency, a dependency record is generated. The dependency record includes dependency information describing the object dependency between the reference object and the referenced object. The dependency record is stored in a database of dependency records.Type: GrantFiled: March 9, 2023Date of Patent: March 12, 2024Assignee: Snowflake Inc.Inventors: Raja Suresh Krishna Balakrishnan, Khalid Zaman Bijon, Subramanian Muralidhar, David Schultz, Jian Xu

Publication number: 20240028591Abstract: A data platform that implements memoizable functions for database objects. The data platform detects a first execution of a memoizable function and generates a first key based on metadata of one or more database objects operated on by the memoizable function and generates a first result for the memoizable function based on the one or more database objects. The data platform detects a second execution of the memoizable function and generates a second key based on the metadata of the one or more database objects operated on by the memoizable function. When the first key and the second key are equal, the data platform reuses the first result of the memoizable function. When the first key and second key do not match, the data platform generates a second result for the second execution of the memoizable function.Type: ApplicationFiled: September 29, 2023Publication date: January 25, 2024Inventors: Raja Suresh Krishna Balakrishnan, Thierry Cruanes, Yujie Li, Subramanian Muralidhar, David Schultz, Jiaqi Yan

Patent number: 11868496Abstract: This disclosure provides methods and techniques of referencing row access policy (RAP) protected mapping tables in a RAP for a data table are disclosed herein. An example method of referencing a mapping table in a data table using nested RAP includes defining, by a processing device, a first access policy for the mapping table to control access by specific users or under specific conditions. The processing device further defines a second access policy attached to the data table referencing the mapping table. The processing device in response to a query, executes the second access policy of the data table to provide a response or operation of data associated with the data table and the mapping table. Executing the second access policy invokes executing the first access policy of the mapping table.Type: GrantFiled: July 28, 2023Date of Patent: January 9, 2024Assignee: Snowflake Inc.Inventors: Raja Suresh Krishna Balakrishnan, Jashua Gupta, Jian Xu

Patent number: 11809591Abstract: Systems and methods for managing column hiding are provided. The systems and methods receive, from a client device, a query associated with a table. The systems and methods determine an access restriction associated with the client device. The systems and methods identify a column of the table that is restricted by the access restriction associated with the client device. In response to identifying the column of the table that is restricted by the access restriction associated with the client device, the systems and methods provide a result of the query that excludes data corresponding to the column.Type: GrantFiled: February 22, 2023Date of Patent: November 7, 2023Assignee: Snowflake Inc.Inventors: Raja Suresh Krishna Balakrishnan, Khalid Zaman Bijon, Subramanian Muralidhar, David Schultz, Jian Xu

Patent number: 9742738Abstract: In one embodiment, a method includes providing a request to store at least a first piece of data. The request to store the first piece of data is a request to store the first piece of data in a first encrypted form on a cloud associated with the cloud application provider. The method also includes determining whether the cloud application provider is capable of encrypting the first piece of data, and providing the first piece of data to the cloud application provider if it is determined that the cloud application provider is capable of encrypting the first piece of data. If it is determined that the cloud application provider is not capable of encrypting the first piece of data, the method further includes encrypting the first piece of data to create the first encrypted form and providing the first encrypted form to the cloud application provider.Type: GrantFiled: June 17, 2014Date of Patent: August 22, 2017Assignee: Cisco Technology, Inc.Inventors: Raja Suresh Krishna Balakrishnan, Vineet Bhan, Rahul Gopi
