Patent number: 11372740Abstract: Systems, methods, and devices for retrying a query. A method includes receiving, by a first database query manager, a query directed to database data from a client account. The method includes assigning an original execution of the query to one or more execution nodes of an execution platform. The method includes determining the original execution of the query was unsuccessful. The method includes transferring the query to a second database query manager configured to manage internal tasks for improving operation of a database platform that are not received from client accounts. The method includes assigning, by the second database query manager, a retry execution of the query to one or more execution nodes of an execution platform.Type: GrantFiled: August 31, 2020Date of Patent: June 28, 2022Assignee: Snowflake Inc.Inventors: Benoit Dageville, Johan Harjono, Simon Holm Jensen, Kunal Prafulla Nabar, Steven James Pelley

Patent number: 11347550Abstract: Techniques described herein can optimize usage of computing resources in a data system. Dynamic throttling can be performed locally on a computing resource in the foreground and autoscaling can be performed in a centralized fashion in the background. Dynamic throttling can lower the load without overshooting while minimizing oscillation and reducing the throttle quickly. Autoscaling may involve scaling in or out the number of computing resources in a cluster as well as scaling up or down the type of computing resources to handle different types of situations.Type: GrantFiled: August 31, 2021Date of Patent: May 31, 2022Assignee: Snowflake Inc.Inventors: Johan Harjono, Daniel Geoffrey Karp, Kunal Prafulla Nabar, Rares Radut, Arthur Kelvin Shi

Patent number: 11321209Abstract: Disclosed herein are systems and methods for query-attempt assignment in a database environment. In an embodiment, a database platform includes first and second database query managers respectively configured to manage external and internal tasks of the database platform. The first database query manager receives a query directed to database data in a client account of the database platform, and an attempt to execute the query is assigned to one or more execution nodes. Based on determining that the attempt was unsuccessful, the database platform transfers the query to the second database manager, which assigns a first retry attempt to execute the query to one or more execution nodes.Type: GrantFiled: January 6, 2021Date of Patent: May 3, 2022Assignee: Snowflake Inc.Inventors: Benoit Dageville, Johan Harjono, Simon Holm Jensen, Kunal Prafulla Nabar, Steven James Pelley

Publication number: 20220083534Abstract: Systems, methods, and devices for retrying a query. A method includes receiving a query directed to database data and assigning execution of the query to one or more execution nodes of an execution platform, the one or more execution nodes configured to execute the query on a first version of a database platform. The method includes determining that execution of the query was unsuccessful. The method includes assigning a first retry execution of the query to the one or more execution nodes of the execution platform and determining whether a regression or an intermittent fault caused the execution of the query to be unsuccessful based at least in part on whether the first retry execution of the query was successful or unsuccessful.Type: ApplicationFiled: November 29, 2021Publication date: March 17, 2022Inventors: Benoit Dageville, Johan Harjono, Kunal Prafulla Nabar, Steven James Pelley

Patent number: 11099962Abstract: Systems, methods, and devices for retrying a query. The method includes receiving from a client a query directed to database data stored on a database platform the query being received by a first component of the database platform. The method includes making by the first component an attempt to execute the query and based on determining that the attempt to execute the query was unsuccessful, the first component sending a query retry job to a second component of the database platform. The method includes selecting by the second component based at least in part on the indicated version of the database platform a version of the database platform on which to attempt a first retry attempt to execute the query.Type: GrantFiled: March 12, 2021Date of Patent: August 24, 2021Assignee: Snowflake Inc.Inventors: Benoit Dageville, Johan Harjono, Simon Holm Jensen, Kunal Prafulla Nabar, Steven James Pelley

Patent number: 11055193Abstract: Systems, methods, and devices for automatically retrying a query. A method includes receiving a query directed to database data and assigning execution of the query to one or more execution nodes of a database platform. The method includes determining that execution of the query was unsuccessful. The method includes assigning a first retry execution of the query on the first version of the database platform and assigning a second retry execution of the query on a second version of the database platform.Type: GrantFiled: October 28, 2020Date of Patent: July 6, 2021Assignee: Snowflake Inc.Inventors: Benoit Dageville, Johan Harjono, Simon Holm Jensen, Kunal Prafulla Nabar, Steven James Pelley

Patent number: 10997050Abstract: Systems, methods, and devices for retrying a query. A method includes receiving from a client account a query directed to database data associated with the client account. The method includes determining that the attempt to execute the query is unsuccessful and making retry attempts to execute the query until making a retry attempt that is successful. The method includes logging each retry attempt and generating a filtered transaction log at least in part by filtering out from the transaction log each unsuccessful attempt to execute the query and providing the filtered transaction log to the client account.Type: GrantFiled: October 28, 2020Date of Patent: May 4, 2021Assignee: Snowflake Inc.Inventors: Benoit Dageville, Johan Harjono, Simon Holm Jensen, Kunal Prafulla Nabar, Steven James Pelley
