Publication number: 20240394187Abstract: Reclamation of a portion of a cache memory in a cloud computing environment is described herein. A cache activeness signal is received from a cache broker. The cache activeness signal is representative of a usage of a first set of cache entries of the cache memory by a first group of computing nodes in a cluster of nodes. A determination to reclaim a portion of the first set of cache entries or of a second set of cache entries is made based at least on the cache activeness signal. The second set of cache entries are utilized by a second group of computing nodes in the cluster of nodes. The determined portion of memory is reclaimed. In an aspect, the cache broker determines a usage of the set of cache entries by the first group of computing nodes and generates the cache activeness signal representative of the determined usage.Type: ApplicationFiled: May 26, 2023Publication date: November 28, 2024Inventors: Junfeng DONG, Ajay KALHAN, Michael E. HABBEN, John M. OSLAKE, Preetham Melavarige GOPALAKRISHNA, Dhrumilkumar Utpalbhai SHAH, Purvi SHAH

Patent number: 11595319Abstract: Techniques for differential overbooking on a cloud database. These techniques may include determining a reservation amount of a multi-tenant resource for a first service of a based upon an overbooking characteristic of the first service, and determining that a total usage value of the multi-tenant resource by a plurality of services is greater than a threshold value. In addition, the techniques may include determining a service usage value of the multi-tenant resource by the first service, determining a first overage value of the first service based on the service usage value and the reservation amount, and performing a resource reclamation process over the multi-tenant resource based on the first overage value of the first service.Type: GrantFiled: December 21, 2020Date of Patent: February 28, 2023Assignee: Microsoft Technology Licensing, LLCInventors: Changsong Li, Ajay Kalhan, Pankaj Arora, Junfeng Dong, Yi Shan, Christian Konig, Manoj Syamala, Vivek Narasayya, Shize Xu, 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.

Patent number: 10417521Abstract: A system and method for material handling are disclosed. The system includes a platform for receiving a plurality of articles, a plurality of sorting bins that each correspond to an article type, an object recognition system for identifying the article on the platform and categorizing the article by a specific article type, and an article engagement assembly. The object recognition system includes a 3D detector for detecting the article and a database containing data on characteristics of article types. The 3D detector is arranged to capture at least one two-dimensional image, and at least one depth image of the article. The article engagement assembly engages and delivers the article to the corresponding sorting bin. The object recognition system is arranged to identify the article based upon the data within the database and instructs the article engagement assembly to engage and place the article in the sorting bin.Type: GrantFiled: September 12, 2014Date of Patent: September 17, 2019Assignee: JCS-Echigo Pte LtdInventor: Junfeng Dong

Patent number: 9009196Abstract: Aspects of the subject matter described herein relate to database access. In aspects, a request for access to a database is received at a node of a database cluster. Also received at the node is an intent associated with the request. If the intent is to potentially write to the database, a primary instance of the database services the request. If the intent is to read from but not write to the database, an identifier of a secondary instance of the database is sent to the requestor for use in accessing the database.Type: GrantFiled: July 13, 2011Date of Patent: April 14, 2015Assignee: Microsoft Technology Licensing, LLCInventors: Raghu Ram, Rohan Samuel Lam, Chadwin J.
