Twitter open sources Storm-Hadoop hybrid called Summingbird

Twitter open sources Storm-Hadoop hybrid called Summingbird | webDEVILopers | Scoop.it
Twitter has open sourced a “streaming MapReduce” system called Summingbird that makes Hadoop and Storm play nicer together so applications that require both batch and stream processing can do their jobs with as little complexity as possible.
webDEVILopers's insight:

In the case of Twitter, Hadoop handles batch processing, Storm handles stream processing, and the hybrid system is called Summingbird. It’s not a tool for every job, but it sounds pretty handy for those it’s designed to address. Hybrid systems like this are actually becoming more common as companies realize they can’t survive in a real-time world with Hadoop alone.

Solution: Create a factory method and use it to replace constructor calls.
