Greg Hogan created FLINK-3277: --------------------------------- Summary: Use Value types in Gelly API Key: FLINK-3277 URL: https://issues.apache.org/jira/browse/FLINK-3277 Project: Flink Issue Type: Improvement Components: Gelly Affects Versions: 1.0.0 Reporter: Greg Hogan
This would be a breaking change so the discussion needs to happen before the 1.0.0 release. I think it would benefit Flink to use {{Value}} types wherever possible. The {{Graph}} functions {{inDegrees}}, {{outDegrees}}, and {{getDegrees}} each return {{DataSet<Tuple2<K, Long>>}}. Using {{Long}} creates a new heap object for every serialization and deserialization. The mutable {{Value}} types do not suffer from this issue when object reuse is enabled. I lean towards a preference for conciseness in documentation and performance in examples and APIs. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
