Patent number: 11934389Abstract: Materialized views may be generated at a managed materialized view platform that accepts data streams as a source. When updating a materialized view with a data stream as a source, a stored portion of the stream is used to maintain a history of changes to be made. When a join operation needs to utilize the data stream source to determine an update to the materialized view, the data stream is preserved to complete the join and update the materialized view.Type: GrantFiled: April 15, 2022Date of Patent: March 19, 2024Assignee: Amazon Technologies, Inc.Inventors: Rohan Deshpande, Yannis Papakonstantinou, Omer Ahmed Zaki, Karthik Gurumoorthy Subramanya Bharathy, Rajib Dugar, Shivateja Reddy Ummenthala

Patent number: 11899659Abstract: The maintenance of a materialized view created and managed by a materialized view management platform may be dynamically adjusted. The performance of updates to a materialized view are monitored to trigger different events to make adjustments to the performance of subsequent updates. The materialized view management platform can adequately scale to handle changes to data sources as inputs to the maintenance of the materialized view, as well as make other adjustments handle various changes in the capability of the target data store to receive updates to the materialized view (e.g., target data store outages).Type: GrantFiled: November 29, 2019Date of Patent: February 13, 2024Assignee: Amazon Technologies, Inc.Inventors: Rohan Deshpande, Yannis Papakonstantinou, Omer Ahmed Zaki, Karthik Gurumoorthy Subramanya Bharathy, Rajib Dugar, Shivateja Reddy Ummenthala

Patent number: 11874828Abstract: Managed materialized views may be generated from across heterogeneous data sources. A request to create a materialized view may be received and performed by a materialized view management platform, which may obtain and generate the materialized view from different data sources and store the materialized view in a target system. Changes to the data sources may be obtained at the materialized view management platform and updates to the materialized view may be determined. The materialized view in the target system may be updated.Type: GrantFiled: September 3, 2021Date of Patent: January 16, 2024Assignee: Amazon Technologies, Inc.Inventors: Rohan Deshpande, Yannis Papakonstantinou, Omer Ahmed Zaki, Karthik Gurumoorthy Subramanya Bharathy, Rajib Dugar, Shivateja Reddy Ummenthala

Patent number: 11544286Abstract: A materialized view created by a materialized view management platform may be replicated across many different target systems. The materialized view management platform allows users to specify different target systems. To create the materialized view in the different target systems, the materialized view management platform can translate the materialized view into different formats in order to store the materialized view in the different formats. Updates to the different instances of the materialized view are then made to keep the different materialized view formats in the different target systems up-to-date.Type: GrantFiled: November 29, 2019Date of Patent: January 3, 2023Assignee: Amazon Technologies, Inc.Inventors: Rohan Deshpande, Yannis Papakonstantinou, Omer Ahmed Zaki, Karthik Gurumoorthy Subramanya Bharathy, Rajib Dugar, Shivateja Reddy Ummenthala

Patent number: 10657154Abstract: Data within a database partition that is being migrated may be made available for access. Data within a database partition may be selected for migration. Writes to the selected data may be prevented while the data is being migrated. Writes to other data, or read access any of the partition, may be allowed during the migration of the selected data. Rollback events may be detected for a database partition that is being migrated, halting the further selection of data for migration and deleting the successfully migrated data at the copy of the database partition being created.Type: GrantFiled: August 1, 2017Date of Patent: May 19, 2020Assignee: Amazon Technologies, Inc.Inventors: Rajib Dugar, Qu Chen, Suraj Narkhede, Aseem Cheema, Kevin Robert McGehee

Patent number: 10534652Abstract: Given a current configuration of virtual node groups in a computing cluster and a new configuration indicating one or more changes to the virtual node groups, a cluster manager generates a reconfiguration plan to arrange virtual nodes into the desired virtual node groups of the new configuration while minimizing a number of virtual nodes to be moved between physical nodes in the computing cluster.Type: GrantFiled: June 29, 2017Date of Patent: January 14, 2020Assignee: Amazon Technologies, Inc.Inventors: Rajib Dugar, Ashish Manral, Ganesh Narayanan
