-------------------------------
Summary: Add support to cache intermediate results (was: Trigger recycling
of buffers held by historic intermediate result partitions)
> Add support to cache intermediate results
> -----------------------------------------
>
> 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.
