QEF - Query Evaluation Framework

Launch
2010


The QEF framework provides a Query Execution Environment Framework that helps users define and execute several types of requests. By "request", we mean a set of user defined operations or functions. Our system manages the execution of the request in a distributed environment (Grid environment), the communication between query execution components, and the access to heterogeneous data sources.


Main Characteristics:

  • Based on Query Engine Framework.
  • Extensible: Application Algebra, Control Flow Operators, Heterogeneous Data Support.
  • Distributed and Parallel Execution.
  • Automatic, Adaptive Scheduling of Operators.
