[jira] [Created] (FLINK-8371) Buffers are not recycled in a non-spilled SpillableSubpartition upon release

Nico Kruber created FLINK-8371:
----------------------------------

             Summary: Buffers are not recycled in a non-spilled SpillableSubpartition upon release
                 Key: FLINK-8371
                 URL: https://issues.apache.org/jira/browse/FLINK-8371
             Project: Flink
          Issue Type: Bug
          Components: Network
    Affects Versions: 1.3.2, 1.4.0, 1.3.1, 1.2.1, 1.3.0, 1.2.0
            Reporter: Nico Kruber
            Assignee: Nico Kruber


{{SpillableSubpartition}} only recycles buffers in its {{buffer}} queue if there is no view attached to it yet. If there is a view, it delegates this task to the view, but {{SpillableSubpartitionView}} only instructs the {{SpilledSubpartitionView}} to clean up in its {{releaseAllResources()}}.

Similarly to the {{PipelinesSubpartition}} implementation, we should always clean up and recycle the buffers in {{SpillableSubpartition#release()}}.
