This is the only interesting paragraph from InfoWorld’s article “Twitter’s programmers speed Hadoop development“:
Three Twitter teams are using Cascading in combination with programming languages: The revenue team uses Scala, the publisher analytics team uses Clojure, and the analytics team uses Jython.
Each of these combinations led to new projects:
Scala + Cascading => Scalding
Clojure + Cascading => Cascalog
Jython + Cascading => PyCascading
An interesting question I couldn’t answer is why each team prefers a different language. My hypothesis:
Scala with its strong typing for handling clear models generating numbers that must always be correct.
Clojure for designing new analysis models
Jython enables quick experimentation with data.
Your thoughts?
