kandi X-RAY | kaylee Summary
Kaylee is a small MapReduce implementation mostly meant as a proof of concept to illustrate the power of ZeroMQ and for education purpose. My goal was not to write a Hadoop clone but to build a starting point that one could use to learn about MapReduce. The main bottleneck in this implementation is that the Shuffle phase requires all data to be moved back to the `Server` instance which is not generally a good idea for performance. But this lets us a implement a simple shuffler using a Python defaultdict in just a few lines of code which is easy to understand.
