> Flink currently allocates a sizeable chunk of the JVM heap for the framework, where hashing
and sorting is done amongst others. This enables graceful spilling to disk, when this datasize
exceeds memory, however might be counterproductive for jobs with large user state and is completely
unutilized by streaming at the moment.
