Patent number: 11962474Abstract: A method (1000) for performance modeling of a plurality of microservices (215) includes deploying the plurality of microservices (215) within a network (1260). The plurality of microservices (215) are communicatively coupled to generate at least one service chain (310) for providing at least one service. Based on a resource allocation configuration, an initial set of training data for the plurality of microservices within the network (1260) is determined. At least a portion of data is excluded from the initial set of training data to generate a subset of training data. A Quality of Service (QoS) behaviour model is generated based on the subset of the training data.Type: GrantFiled: October 2, 2019Date of Patent: April 16, 2024Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Michel Gokan Khan, Wenfeng Hu, Carolyn Cartwright, Huiyuan Wang

Patent number: 11960468Abstract: A database management system receives a command defining a view of the database. The view definition is accepted without determining whether references to schema elements within the view definition are resolvable to existing elements of the database schema. A query of the view is received. In response to the query of the view, the database management system resolves references to schema elements in the view definition by determining whether the references correspond to data available for processing the query.Type: GrantFiled: May 17, 2018Date of Patent: April 16, 2024Assignee: Amazon Technologies, Inc.Inventors: Huiyuan Wang, Meng Tong, Naresh Kishin Chainani, Mengchu Cai
