摘要： Page feed for efficient dataflow between distributed query engines is disclosed. An example method comprises storing a query result relation by a producer query as pages in a query engine buffer pool, and then sending these pages to a distributed caching platform (DCP) as the data source of another query. The example method also includes reading the result relation by a consumer query from the page stored in the DCP.

摘要： 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.

摘要： 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.

摘要： A nested chain of densest subgraphs is derived by a computer from a given graph that has multiple vertices and edges. The two ends of each edge are assigned with respective incident weights, and each vertex is given a vertex weight. A weight balancing process is carried out by the computer to iteratively go through the edges to adjust the incident weights of each edge and the vertex weights of the vertices connected by that edge to reduce a difference between the vertex weights of the two vertices. After the balancing, the vertex weights are put in an ordered sequence according to their values, and a nested chain of densest subgraphs is derived from the ordered sequence.
