Pretty cool! It will be really useful once there is better support for types: 1) some kind of type inference/casting/automatic serialization, so that one can write setValue(4) instead of setValue(IntWritable(4)) 2) possibility to implement all algorithm-related classes (vertex/edge/message values, aggregators, combiners, etc) directly in Python If we could use some Python facility for serializing objects, this would become a really high-level API for writing graph algorithms in Python, without dealing with Java boilerplate, serialization, etc. giraph-core/src/main/java/org/apache/giraph/conf/AbstractConfOption.java <https://reviews.apache.org/r/11709/#comment44869> Isn't this a bit redundant? !isPresent seems convenient enough. Also, isSet could be a more standard name, giraph-core/src/main/java/org/apache/giraph/jython/Jython.java <https://reviews.apache.org/r/11709/#comment44870> This Javadoc is a bit misleading, because the class doesn't implement Computation. Also, the name Jython doesn't convey much. Maybe something like JythonUtils or JythonRunner... - Alessandro Presta On June 10, 2013, 6:55 a.m., Nitay Joffe wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
