Using Computing Resources To Perform Database Queries According To A Dynamically Determined Query Size

View page
US Patent:
20190384845, Dec 19, 2019
Filed:
Jun 13, 2018
Appl. No.:
16/007697
Inventors:
- Seattle WA, US
George Constantin Caragea - Redwood City CA, US
Naresh Kishin Chainani - Mountain View CA, US
Martin Grund - Lafayette CA, US
Assignee:
Amazon Technologies, Inc. - Seattle WA
International Classification:
G06F 17/30
Abstract:
Database queries may be performed using resources based on a determined size of the database query. Database query size may be dynamically determined for a database query when the query is received. The database query may be assigned to resources used for database queries of the determined size. In some embodiments, timeouts may be applied to reassign database queries to different resources if the performance of the database query exceeds a timeout threshold.

Precisely Tracking Memory Usage In Multi-Process Computing Environment

US Patent:
20180335952, Nov 22, 2018
Filed:
Jul 30, 2018
Appl. No.:
16/049468
Inventors:
- San Francisco CA, US
George Constantin Caragea - San Mateo CA, US
Carlos Garcia-Alvarado - San Jose CA, US
Michail Petropoulos - San Francisco CA, US
International Classification:
G06F 3/06
G06F 17/30
G06F 9/50
G06F 9/48
Abstract:
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for precisely tracking memory usage in a multi-process computing environment. One of the methods includes implementing an instance of a memory usage tracker (MUT) in each process running in a node of a computer system. A MUT can maintain an account of memory usage for each of multiple logical owners running on a process on which the MUT is running. The MUT can determine an actual memory quota for each owner, and enforce the actual memory quota of the owner. Enforcing the actual memory quota of the owner can include receiving each memory allocation request, checking each allocation request and a current state of the account against the actual quota, approving or rejecting each allocation request, communicating the approval or rejection to an underlying memory manager, and updating the owner account for each approved allocation request.
