Summary: Change memory management settings for Streaming programs
Key: FLINK-1368
URL: https://issues.apache.org/jira/browse/FLINK-1368
Project: Flink
Issue Type: Improvement
Components: Streaming
Affects Versions: 0.9
Reporter: Gyula Fora
Currently streaming programs use the same memory management settings as a batch
api by reserving a large share of the heap for the runtime, while not making
any use of it.
This should be disabled until the streaming runtime is reworked so it makes a
good use of this reserved space. One part where this could be most relevant is
windowing operators where a large time window could easily cause memory
problems with the current implementation. For windowing disk spilling should be
implemented to increase robustness.
