  • DATA STREAM PROCESSING BASED ON A BOUNDARY PARAMETER
    Publication number: 20160253219
    Abstract: In one implementation, a system for processing a data stream can comprise a station engine, an execution engine, and a synchronize engine. A station engine can provide a stream operator to receive application logic, punctuate the data stream, and determine a number of input channels for parallel processing. The execution engine can perform a behavior of the application logic during a process operation. The synchronize engine can hold data of the data stream associated with a window until each input channel has reached a data boundary based on a boundary parameter.

  • Processing a data stream
    Patent number: 9405801
    Abstract: Methods, database management systems (“DBMS”) and computer-readable media are provided for processing unbounded stream data using a traditional DBMS. Execution of a query that includes a data stream as a data source may be initiated. Tuples may be processed in accordance with the query as the tuples are received through the data stream until an indication is received that execution of the query should cease.

  • FAILURE RECOVERY OF A TASK STATE IN BATCH-BASED STREAM PROCESSING
    Publication number: 20160196188
    Abstract: Described herein are techniques for failure recovery of a task state in batch-based stream processing. A message including a batch of tuples can be unpacked into component tuples. The component tuples can be processed at a task node. A failure-recovery checkpoint of a state of the task node can be generated before all of the component tuples have been processed.

  • MAP WITH DIFFERENT DEGREES OF OVERLAPPING GEOCODED PIXELS
    Publication number: 20160170611
    Abstract: A pattern of geocoded pixels is generated by accessing data point values, where each data point value includes an attribute value and coordinates of a geographic location. Each data point value corresponds to a geocoded pixel that is positioned on the pattern based on the coordinates of the data point value such some geocoded pixels overlap other geocoded pixels. Different levels of the pattern of geocoded pixels correspond to a different degree of overlap between the geocoded pixels. The different levels of the pattern of geocoded pixels are associated with different magnification levels of a geographic map such that changing a magnification level of the geographic map causes a degree of overlap between the geocoded pixels of the pattern to change.

  • Functional-form queries
    Patent number: 9361341
    Abstract: Middleware is integrated within a database engine. The middleware is to execute a functional-form query representing a dataflow graph comprising queries and relation valued functions. The middleware is to interact with the database engine to cause the database engine to execute the queries. Each relation valued function receives a plurality of first relations as input and generates a second relation as output.

  • Visualizing a relationship of attributes using a relevance determination process to select from candidate attribute values
    Patent number: 9280612
    Abstract: For plural categorical values of a first attribute, more relevant categorical values of a second attribute are selected from among candidate categorical values of the second attribute, where the selecting uses a relevance determination process that considers frequencies of occurrence of respective pairs of the categorical values of the first and second attributes. A visualization that includes groups of cells corresponding to the respective pairs of categorical values of the first and second attributes is generated. At least one of the groups includes cells assigned visual indicators based on values of a third attribute.
