[jira] [Updated] (FLINK-3853) Reduce object creation in Gelly utility mappers

     [ https://issues.apache.org/jira/browse/FLINK-3853?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Greg Hogan updated FLINK-3853:
------------------------------
    Description: 
Gelly contains a set of {{MapFunction}} between {{Vertex}} and {{Tuple2}} and between {{Edge}} and {{Tuple3}}. A {{Vertex}} is a {{Tuple2}} and an {{Edge}} is a {{Tuple3}}, and conversion in the opposite direction can be performed with a single object per {{MapFunction}}.

This only applies to the Gelly Java API. Scala tuples are not related to {{Vertex}} or {{Edge}}.
