> When SimpleCollectingOutputView is used, records are collected into a
> pre-allocated MemorySegmentSource.
> In case of depletion, the SimpleCollectingOutputView#nextSegment method
> throws EOFException without a message.
> This can be non-obvious to diagnose as a newcomer, as
> * the Java SDK documentation strongly suggests EOFException is related to an
> inability to read further (whereas in this context, the exception
> materializes an inability to _write_ further)
> * awareness than pre-allocated, fixed-size buffers are in play may not
> necessarily be expected of a newcomer to flink.
