Twister: Iterative MapReduce

Created by a team of Ph.D’s from the Indiana Univesity, Twister is a set of extensions to the MapReduce programming model:

  • Distinction on static and variable data
  • Configurable long running (cacheable) map/reduce tasks
  • Pub/sub messaging based communication/data transfers
  • Efficient support for Iterative MapReduce computations (extremely faster than Hadoop or Dryad/DryadLINQ)
  • Combine phase to collect all reduce outputs
  • Data access via local disks
  • Lightweight (~5600 lines of Java code)
