Patent number: 9304809Abstract: Disclosed are systems and methods for processing events in an event stream using a map-update application. The events may be embodied as a key-attribute pair. An event is processed by one or more instances implementing either a map or an update function. A map function receives an input event from the event stream and publishes one or more events to the event stream. An update function receives an event and updates a corresponding slate and publishes zero or more events. Systems and methods are also disclosed herein for implementing a map-update application in a multithreaded architecture and for handling overloading of a particular thread or node. Systems and methods for providing access to slates updated according to update operations are also disclosed.Type: GrantFiled: July 19, 2012Date of Patent: April 5, 2016Assignee: Wal-Mart Stores, Inc.Inventors: Wang Chee Lam, Lu Liu, Taraka Subrahmanya Prasad Siripurapu, Anand Rajaraman, Zoheb Vacheri, AnHai Doan

Publication number: 20140059185Abstract: Exemplary embodiments allow performance of stream computations on real-time data streams using one or more map operations and/or one or more update operations. A map operation is a stream computation in which stream events in one or more real-time data streams are processed in a real-time manner to generate zero, one or more new stream events. An update operation is a stream computation in which stream events in one or more real-time data streams are processed in a real-time manner to create or update one or more static “slate” data structures that are stored in a durable manner.Type: ApplicationFiled: October 31, 2013Publication date: February 27, 2014Applicant: Wal-Mart Stores, Inc.Inventors: Taraka Subrahmanya Prasad Siripurapu, Wang Chee Lam, Digvijay Singh Lamba, Anand Rajaraman
