Patent number: 11983165Abstract: Embodiments of the present disclosure provide techniques for deduplicating files during internal stage replication using a directory table of the replicated internal stage that is modified as a cache for storing and retrieving original file-level metadata for the replicated files. An initial list of candidate files for loading from the internal stage to a table of the target deployment is prepared based on the files listed in the internal stage, and refined using a directory table lookup. If there is any inconsistency between the files registered in the directory table and the files listed in the internal stage, the target deployment will inspect the user-defined file-level metadata to obtain original file-level metadata for each file that is present in the internal stage but not in the directory table. This information may be used during deduplication to ensure that no duplicate files are loaded.Type: GrantFiled: March 29, 2023Date of Patent: May 14, 2024Assignee: Snowflake Inc.Inventors: Abdullah Al Mahmood, Chong Han, Ganeshan Ramachandran Iyer, Jiaxing Liang, Nithin Mahesh, Yanrui Zhang

Publication number: 20240095060Abstract: Systems and methods are taught for providing customers of a cloud computing service to control when updates affect the services provided to the customers. Because multiple customers share the cloud's infrastructure, each customer may have conflicting preferences for when an update and associated downtime occurs. Preventing and resolving conflicts between the preferences of multiple customers while providing them with input for scheduling a planned update may reduce the inconvenience posed by updates. Additionally, the schedule for the update may be transmitted to customers so that they can prepare for the downtime of services associated with the update.Type: ApplicationFiled: November 28, 2023Publication date: March 21, 2024Applicant: Microsoft Technology Licensing, LLCInventors: Jiaxing ZHANG, Thomas MOSCIBRODA, Haoran WANG, Jurgen Aubrey WILLIS, Yang CHEN, Ying YAN, James E.

Patent number: 11100412Abstract: Implementations of the present specification provide a method and an apparatus for extending question and answer samples. According to the method, a random number is generated for each existing sample, a question is blurred for a sample whose random number belongs to sample extension random numbers, to generate an extended sample, so that an overall sample blurring extension rate can be effectively controlled. In addition, for a sample needing blurring extension, a question is extended by deleting a word with a predetermined part of speech in the corresponding question, and then an extended sample is generated based on an extended question, so that more question expression ways are compatible. As such, a question and answer model is trained by using a sample set to which extended samples are added, so that an answer can be provided to a user more effectively.Type: GrantFiled: March 13, 2020Date of Patent: August 24, 2021Assignee: Advanced New Technologies Co., Ltd.Inventors: Kaisheng Yao, Jiaxing Zhang, Jia Liu, Xiaolong Li
