[jira] [Created] (FLINK-2140) Access the number of vertices from
within the GSA functions
Andra Lungu created FLINK-2140:
----------------------------------
Summary: Access the number of vertices from within the GSA functions
Key: FLINK-2140
URL: https://issues.apache.org/jira/browse/FLINK-2140
Project: Flink
Issue Type: New Feature
Components: Gelly
Affects Versions: 0.9
Reporter: Andra Lungu
Similarly to the Vertex-centric approach we would like to allow the user to access the number of vertices from the Gather, Sum and Apply functions respectively. This property will become available by setting [setOptNumVertices()] the numVertices option to true.
The number of vertices can then be accessed in the gather, sum and apply functions using the getNumberOfVertices() method. If the option is not set in the configuration, this method will return -1.
