Customizable Parallel Execution of Scientific Stream Queries

  title={Customizable Parallel Execution of Scientific Stream Queries},
  author={Milena Ivanova and Tore Risch},
Scientific applications require processing high-volume on-line streams of numerical data from instruments and simulations. We present an extensible stream database system that allows scalable and flexible continuous queries on such streams. Application dependent streams and query functions are defined through an Object-Relational model. Distributed execution plans for continuous queries are described as high-level data flow distribution templates. Using a generic template we define two… CONTINUE READING
