----------------------------------
Summary: Make IntermediateResultPartitionManager aware of consumed
partitions
Key: FLINK-1359
URL: https://issues.apache.org/jira/browse/FLINK-1359
Project: Flink
Issue Type: Improvement
Components: Distributed Runtime
Reporter: Ufuk Celebi
Assignee: Ufuk Celebi
The current state of runtime support for intermediate results (see
https://github.com/apache/incubator-flink/pull/254 and FLINK-986) does not
distinguish between historic and currently produced/consumed intermediate
result partitions (e.g. only non-persistent intermediate results) in the
intermediate result partition manager.
For persistent intermediate results we need to distinguish between currently
consumed results and those that have already been produced and consumed. As a
first step, historic results can be evicted based on least recent use.
