Publication number: 20200034157Abstract: A dataflow controller technology. A dataflow execution graph (such as a directed acyclic graph) receives or is to receive one or more data streams for processing. The control of the dataflow execution graph is performed by a set of one or more dataflow controllers that are dedicated to that dataflow execution graph. Each dataflow execution graph is instantiated and assigned to the dataflow execution graph such that the assignment results in the dataflow controller executing dataflow control functions for that dataflow execution graph. By dedicating controller(s) to only one dataflow execution graph, the risk of failure of the controller is bound to a single dataflow execution graph.Type: ApplicationFiled: July 25, 2018Publication date: January 30, 2020Inventors: Rahul POTHARAJU, Terry Yumin KIM

Publication number: 20200034185Abstract: At least some embodiments described herein relate to the automatic tuning of a dataflow execution graph. Such dataflow execution graphs are often used to execute some processing against a stream of data messages. A performance parameter of the dataflow execution graph is monitored, and compared against a service level objective. Based on the comparison, it is automatically decided whether a configuration of the dataflow execution graph should be changed. If a change is decided to be made, the configuration of the dataflow execution graph is altered. Thus, rather than require explicit instructions to change the configuration of a dataflow execution graph, the configuration of a dataflow execution graph is changed (or tuned) depending on compliance of performance with a service level objective.Type: ApplicationFiled: July 25, 2018Publication date: January 30, 2020Inventors: Rahul POTHARAJU, Terry Yumin KIM

Patent number: 10545999Abstract: Disclosed herein is a system and method for generating an enhanced index for documents contained in a knowledge base. Documents or configuration snapshots are tokenized and then passed through a number of filters. The filters modify the token stream to generate an enhanced token stream for the document by removing words from the stream and adding domain level knowledge to the tokens in the stream. The token stream is then added to the index for the document so that searches can be completed against the knowledge base when searches are generated from configuration snapshots or from inputted search queries.Type: GrantFiled: June 5, 2017Date of Patent: January 28, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Navendu Jain, Luhui Hu, Liyuan Zhang, Rahul Potharaju, Vitaly Voloshin, Mingshi Wang, Joseph K.

Publication number: 20190370408Abstract: Mechanisms to modify a dataflow execution graph that processes a data stream. An intermediate dataflow execution graph is used during modification of the dataflow execution graph from one configuration (the old dataflow execution graph) to the next (the new dataflow execution graph). Data messages of the data stream may continue to feed into the intermediate dataflow execution graph, thereby reducing latency and maintaining throughput during reconfiguration of the dataflow execution graph. Control message(s) that are structured to accomplish the reconfiguration is/are also passed into the intermediate dataflow execution graph during reconfiguration. As the control message(s) are all processed by the intermediate dataflow execution graph, the intermediate dataflow execution graph assumes the topology of the new dataflow execution graph.Type: ApplicationFiled: May 31, 2018Publication date: December 5, 2019Inventors: Rahul POTHARAJU, Kai ZENG, Paolo COSTA, Terry Yumin KIM, Sudheer DHULIPALLA, Saravanan MUTHUKRISHNAN, Shivaram VENKATARAMAN, Le XU, Lao MAI, Steve D.

Patent number: 10489463Abstract: When a computing device has an issue, a detector receives (or retrieves) data associated with the computing device. The data may include parameter key-value pairs. The detector creates queries based on the data and distributes the queries to one or more matching engines, such as an exact matching engine or a proximity matching engine. The one or more matching engines look for matches in an index of database documents. The results from the one or more matching engines are ranked based on relevancy scores. In some cases, users may provide feedback regarding the relevancy of the results and the feedback may be used to recalibrate how the relevancy scores are determined.Type: GrantFiled: February 12, 2015Date of Patent: November 26, 2019Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Rahul Potharaju, Navendu Jain

Patent number: 9779141Abstract: Disclosed herein is a system and method for searching or processing queries for searching for documents contained in a domain specific knowledge base. The system takes a query and generates from the query a modified version of the query by passing the query through one or more filters in a query processor. The query processor adds or removes terms from the query. The query processor can add or recognize that two words that appear to be separate words actually identify a specific software entity or can determine that a number appearing in a query is not just a number but refers to a specific version or a number relevant to the specific problem.Type: GrantFiled: December 14, 2013Date of Patent: October 3, 2017Assignee: Microsoft Technology Licensing, LLCInventors: Navendu Jain, Luhui Hu, Liyuan Zhang, Rahul Potharaju, Vitaly Voloshin, Mingshi Wang, Joseph K.
