sabarishyam updated GIRAPH-820:
-------------------------------
Description:
In giraph source vertices present only in edge input are created by default.
In this patch an additional configuration parameter has been added to control
this behavior. The default behavior is still to create the source vertex if not
already present, but the user can choose not to do so, by setting
CREATE_VERTEX_IMPLICIT_EDGE_INPUT BoolConfoption to false.
An example use case for/ such a change is to help in creating subgraphs of the
original graph based on a sampled vertex input.
