Subject Memory Management in Streaming mode
Date Mon, 29 Aug 2016 15:53:45 GMT

I have a question regarding memory management in the Streaming mode. The
documents state that the memory management module is only used in the Batch
mode, and Flink Streaming directly operates on JVM heap. Then, what if the
volume of data in a window becomes too large to fit in the heap? Will Flink
spill some data to disk or will it trigger an OOM exception?
