----------------------------------
Summary: Trigger recycling of buffers held by historic
intermediate result partitions
Key: FLINK-1404
URL: https://issues.apache.org/jira/browse/FLINK-1404
Project: Flink
Issue Type: Improvement
Components: Distributed Runtime
Reporter: Ufuk Celebi
Assignee: Ufuk Celebi
With blocking intermediate results (FLINK-1350) and proper partition state
management (FLINK-1359) it is necessary to allow the network buffer pool to
request eviction of historic intermediate results when not enough buffers are
available. With the currently available pipelined intermediate partitions this
is not an issue, because buffer pools can be released as soon as a partition is
consumed.
We need to be able to trigger the recycling of buffers held by historic
intermediate results when not enough buffers are available for new local pools.
