Subject [jira] [Commented] (FLINK-2895) Duplicate immutable object creation
Date Thu, 22 Oct 2015 13:30:27 GMT

    [ https://issues.apache.org/jira/browse/FLINK-2895?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14969154#comment-14969154

Greg Hogan commented on FLINK-2895:

With immutable objects, when object reuse is enabled a single unused object is created. When
object reuse is disabled we are creating an unused object for every object deserialization.

> Inverse of FLINK-2724. When object reuse is disabled a few operators are creating and
passing objects locally. In the case of immutable objects these will be discarded by the {{TypeSerializer}}
when deserializing.
