Patent number: 11620179Abstract: According to embodiments of the present disclosure, there is provided a method, apparatus, device, storage medium and program product for log information processing. The method comprises: determining a source of a target log in response to a log query request, wherein the log query request indicates that a target user requests to query the target log; determining a log desensitization policy corresponding to the source of the target log, the log desensitization policy being determined based on log registration information associated with the source, the log registration information being used for indicating a physical meaning of a variable item in the target log; and performing, based on service attribute information of the target user, the log desensitization policy and service authority information, desensitization processing on the variable item related to the target user in the target log for providing the target user with a desensitized target log.Type: GrantFiled: January 26, 2022Date of Patent: April 4, 2023Assignee: BEIJING BYTEDANCE NETWORK TECHNOLOGY CO., LTD.Inventors: Zhipeng Tian, Hengming Dai, Zhijun Ling, Jianqing Zhang, Zhengqin Luo, Xinglang Wang

Patent number: 11422856Abstract: Techniques are disclosed relating to scheduling program tasks in a server computer system. An example server computer system is configured to maintain first and second sets of task queues that have different performance characteristics, and to collect performance metrics relating to processing of program tasks from the first and second sets of task queues. Based on the collected performance metrics, the server computer system is further configured to update a scheduling algorithm for assigning program tasks to queues in the first and second sets of task queues. In response to receiving a particular program task associated with a user transaction, the server computer system is also configured to select the first set of task queues for the particular program task, and to assign the particular program task in a particular task queue in the first set of task queues.Type: GrantFiled: June 28, 2019Date of Patent: August 23, 2022Assignee: PayPal, Inc.Inventors: Xin Li, Libin Sun, Chao Zhang, Xiaohan Yun, Jun Zhang, Frédéric Tu, Yang Yu, Lei Wang, Zhijun Ling

Patent number: 11354295Abstract: Methods and systems for processing incoming data in real-time are described herein. The incoming data is processed in real-time to generate data records that may be improved over time, for example, by automatically correcting inaccurate data in the records. In some embodiments, when data is received, a real-time process is initially performed on the received data under a first time constraint to produce first data for a data record. Subsequently, one or more non-real-time processes are then performed on the received data under a second time constraint to produce second data for the data record. The second data may be used to update the data record, for example, to correct any inaccuracy caused by the real-time process of the received data. Preferably, the second time constraint is longer than the first time constraint.Type: GrantFiled: August 18, 2017Date of Patent: June 7, 2022Assignee: PayPal, Inc.Inventors: Xin Li, Xiaohan Yun, Yunfeng Li, Yang Yu, Zhijun Ling, Ke Zheng, Uri Arad, Frederic Tu

Patent number: 10887729Abstract: A method is provided that includes accessing, by a server provider server of a service provider, a database storing associations between network addresses and locations. Additionally, the method includes determining a subset of the database corresponding to a first network address, each association included in the subset corresponding to an association between the first network address and a respective location. The method also includes in response to determining that the subset of the database satisfies one or more clustering criteria, calculating a representative location corresponding to the first network address, and storing an association between the first network address and the representative location in a second database.Type: GrantFiled: January 21, 2020Date of Patent: January 5, 2021Assignee: PAYPAL, INC.Inventors: Xin Li, Jun Zhang, Yang Yu, Xiaohan Yun, Chao Zhang, Frédéric Tu, Zhijun Ling, Libin Sun, Christopher Tang

Patent number: 10671361Abstract: Technologies relating to determining data variable dependencies to facilitate code execution are disclosed. An example method includes: identifying a set of programming statements having a plurality of data parameters; identifying first data parameters associated with a first programming statement in the set of programming statements; determining one or more parameter dependencies associated with the first data parameters; and determining, based on the one or more parameter dependencies, a first execution performance of the first programming statement. The method may further include: determining a second execution performance of the second programming statement and scheduling execution of the first programming statement and of the second programming statement based on the first and second execution performances.Type: GrantFiled: October 25, 2016Date of Patent: June 2, 2020Assignee: PayPal, Inc.Inventors: Xin Li, Weijia Deng, Shuan Yang, Feng Chen, Jin Yao, Zhijun Ling, Yunfeng Li, Xiaohan Yun, Yang Yu
