------------------------------------
Summary: Gelly API improvements
Key: FLINK-2857
URL: https://issues.apache.org/jira/browse/FLINK-2857
Project: Flink
Issue Type: Improvement
Components: Gelly
Reporter: Vasia Kalavri
During the Flink Forward Gelly School training, I got some really valuable
feedback from participants on what they found hard to grasp or non-intuitive in
the API.
Based on that, I propose we make the following improvements:
- rename the mapper in creation methods to {{VertexInitializer}}, so that its
purpose is easier to understand.
- add a {{fromTuple2DataSet}} method to easily create graphs from {{Tuple2}}
datasets, i.e. edges with no values.
- in {{joinWith*}} methods, it is hard to understand what are the parameters in
the mapper and what will be the output. I suggest we flatten them, try to give
intuitive names and improve the javadocs.
- in neighborhood methods, it is hard to understand what are the arguments of
the {{EdgeFunction.iterateEdges}} and {{ReduceEdgesFunction.reduceEdges}}.
Javadocs and parameter names could be improved here too.
