---------------------------------
Assignee: Greg Hogan
> Enable object reuse in MergeIterator
> ------------------------------------
>
> Key: FLINK-2653
> URL: https://issues.apache.org/jira/browse/FLINK-2653
> Project: Flink
> Issue Type: Improvement
> Components: Distributed Runtime
> Affects Versions: master
> Reporter: Greg Hogan
> Assignee: Greg Hogan
>
> MergeIterator currently discards given reusable objects and simply returns a
> new object from the JVM heap. This inefficiency has a noticeable impact on
> garbage collection and runtime overhead (~5% overall performance by my
> measure).
