---------------------------------
Summary: CopyableValue method to copy into new instance
Key: FLINK-2723
URL: https://issues.apache.org/jira/browse/FLINK-2723
Project: Flink
Issue Type: New Feature
Components: Core
Affects Versions: master
Reporter: Greg Hogan
Assignee: Greg Hogan
Priority: Minor
Provide a method for generic user-defined functions to clone a
{{CopyableValue}}. A common use case is a {{GroupReduceFunction}} that needs to
store multiple objects. With object reuse we need to make a deep copy and with
type erasure we cannot call new.
