  • Support Actual and Virtual SQL Dataflow by Streaming Infrastructure
    Publication number: 20160034535
    Abstract: A method includes binding a stationed operator to a database query engine, wherein the stationed operator comprises system utilities and an open executor to execute user-supplied application logic. The method further includes receiving an unbounded input stream of input tuples by the stationed operator, the stream of input tuples comprising a succession of chunks. The method also includes applying a query defined by the application logic to each successive chunk of the input stream to produce an output packet for each such chunk, and generating an unbounded output stream comprising the output packets.

  • Data staging for results of analytics
    Patent number: 9251215
    Abstract: Data staging for results of analytics according to an example method includes maintaining current results from the analytics in a first data structure, the first data structure having a label identifying first data structure as a target for queries. The method also includes maintaining prior results from the analytics in at least one other data structure. The method also includes changing the label of the first data structure after a predetermined time. The method also includes assigning the label to one of the other data structures, wherein the label identifies the one of the other data structures as the target for queries.

  • Continuous querying of a data stream
    Patent number: 9195708
    Abstract: In continuous querying of a data stream, a query including query cycles can be initialized (310) on a query engine to analyze the data stream for desired information. The data stream can be processed (320) as segments, where a size of the segments is based on a user-defined parameter. The query cycles can be synchronized (330) with the segments of the data stream. A first segment can be analyzed (340) by performing the query on the first segment to obtain a first result. A query state of the query can be persisted (350) and the query operation can be rewound to begin a new query cycle. A second segment can be analyzed (360) in the new query cycle by performing the query on the second segment based on the first result.

  • User Defined Functions Including Requests for Analytics by External Analytic Engines
    Publication number: 20150269234
    Abstract: Described herein are techniques enabling a query engine to process a query comprising a user defined function. The user defined function can include a request for analytics to be performed by an external analytic engine. The query engine can retrieve data from a database in accordance with the query and send the data and instructions to perform the analytics to the external analytic engine. The query engine can then receive analytic results from the external analytic engine.

  • User defined data partitioning (UDP)—grouping of data based on computation model
    Patent number: 8904381
    Abstract: Methods, systems, and computer program products are provided for generating application-aware data partitioning to support parallel computing. A label for a user defined data partitioning (UDP) key is generated by a labeling process to configure data partitions of original data. The UDP is labeled by the labeling process to include at least one key property excluded from the original data. The data partitions are evenly distributed to co-locate and balance the data partitions and corresponding computations performed by computational servers. A data record of the data partitions is retrieved by performing an all-node parallel search of the computational servers using the UDP key.
