> The non-blocking output was introduced in FLINK-14396 and FLINK-14498 to solve the
problem of handling the checkpoint barrier in the case of backpressure.
> In order to make the whole process through, {{StreamInputProcessor}} should be allowed
to process input elements if the output is also available.
> The default core size of {{LocalBufferPool}} for {{ResultPartition}} should also be
increased by 1 in order not to impact the performance in the new way, and this tiny memory
overhead could be ignored in practice.
