Publication number: 20250086086Abstract: A proactive resource allocator in a database management system is configured to make database resource allocation decisions for users accessing a database, including proactively resuming resources reclaimed from a user accessing a database. To determine whether to proactively resume resources that are reclaimed from a user who has logged out, the proactive resource allocator accesses historical data to predict a time the user will log back in. If the probability of the user logging back in is high, the proactive resource allocator reallocates resources to the user at the predicted time and may predict a next time the user will log back in. The proactive resource allocator may then logically pause the resources or may physically pause the resources prior to the next predicted time.Type: ApplicationFiled: October 11, 2023Publication date: March 13, 2025Inventors: Olga POPPE, Qun GUO, Willis LANG, Pankaj ARORA, Ajay KALHAN

Publication number: 20250086012Abstract: A proactive resource allocator in a database management system is configured to make database resource allocation decisions for users accessing a database, including proactively pausing resources allocated to a user for accessing a database. To determine whether to proactively pause resources that are allocated to a user who has logged out, the proactive resource allocator accesses historical data to predict a next time the user with log back in. If the predicted next time of user login is relatively soon, the proactive resource allocator maintains the allocation of the resources to the user. If the predicted next time of user login is relatively far away, the proactive resource allocator pauses the resources. The proactive resource allocator may logically pause the resources or may physically pause the resources.Type: ApplicationFiled: October 11, 2023Publication date: March 13, 2025Inventors: Olga POPPE, Qun GUO, Willis LANG, Pankaj ARORA, Ajay KALHAN

Publication number: 20240061714Abstract: Systems, methods, and devices are described for managing cloud services implemented by one or more clusters in a cloud computing environment. Responsive to receiving a first notification indicating that a cloud service implemented by the one or more clusters has not been used for a first predetermined amount of time, the cloud service is maintained in an active state and metadata is updated that specifies the cloud service is in a deactivated state. The metadata is visible to a user interface of a management portal of the cloud computing environment. Responsive to receiving a second notification indicating that the cloud service has not been used for a second predetermined amount of time following the first predetermined amount of time, a deactivation workflow is instantiated to deactivate the cloud service. In a further aspect, a cloud service engine generates the first and second notifications.Type: ApplicationFiled: August 19, 2022Publication date: February 22, 2024Inventors: Sachin Subraya PANDIT, Qun GUO, Pankaj ARORA, Shize XU, Venkat PARTHASARATHY, Ajay KALHAN, John M.

Publication number: 20230333975Abstract: Intelligent memory brokering for multiple process instances, such as relational databases (e.g., SQL servers), reclaims memory based on value, thereby minimizing cost across instances. An exemplary solution includes: based at least on a trigger event, determining a memory profile for each of a plurality of process instances at a computing node; determining an aggregate memory profile, the aggregate memory profile indicating a memory unit cost for each of a plurality of memory units; determining a count of memory units to be reclaimed; identifying, based at least on the aggregate memory profile and the count of memory units to be reclaimed, a count of memory units to be reclaimed within each process instance so that a total cost is minimized to reclaim the determined count; and communicating, to each process instance having identified memory units to be reclaimed, a count of memory units to be reclaimed within the process instance.Type: ApplicationFiled: June 19, 2023Publication date: October 19, 2023Inventors: Manoj SYAMALA, Vivek NARASAYYA, Junfeng DONG, Ajay KALHAN, Shize XU, Changsong LI, Pankaj ARORA, Jiaqi LIU, John M.

Patent number: 11372770Abstract: Methods for determining cache activity and for optimizing cache reclamation are performed by systems and devices. A cache entry access is determined at an access time, and a data object of the cache entry for a current time window is identified that includes a time stamp for a previous access and a counter index. A conditional counter operation is then performed on the counter associated with the index to increment the counter when the time stamp is outside the time window or to maintain the counter when the time stamp is within the time window. A counter index that identifies another counter for a previous time window where the other counter value was incremented for the previous cache entry access causes the other counter to be decremented. A cache configuration command to reclaim, or additionally allocate space to, the cache is generated based on the values of the counters.Type: GrantFiled: September 9, 2020Date of Patent: June 28, 2022Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Junfeng Dong, Ajay Kalhan, Manoj A.

Patent number: 11256619Abstract: A solution is disclosed for memory management of serverless databases that includes: based at least on detecting a trigger event, determining whether memory is to be reclaimed; based at least on determining that memory is to be reclaimed, determining an amount of memory to be reclaimed; identifying memory to be reclaimed; and reclaiming the identified memory. Disclosed solutions are flexible, enabling customization of the aggressiveness and manner of memory reclamation. This permits users to specify a tailored balance point between performance and cost, for arrangements that bill users based on resource usage (e.g., memory consumed by a serverless database). In some examples, users specify a ramp-down parameter that is used to determine how much memory can be evicted in a particular reclamation event, time intervals (or another criteria) for triggering a reclamation event, and a definition for whether a cache is active.Type: GrantFiled: August 13, 2019Date of Patent: February 22, 2022Assignee: Microsoft Technology Licensing, LLCInventors: Manoj Syamala, Arnd Christian König, Vivek Narasayya, Junfeng Dong, Ajay Kalhan, Shize Xu, Changsong Li, Pankaj Arora, Jiaqi Liu, John M.
