Piotr Nowojski commented on FLINK-19682:
----------------------------------------
We can try to do that, but there will be very little time to implement this
between FLINK-19681 and the feature freeze date. Change will probably be quite
simple, but the implementation will need to start even before FLINK-19681 is
merged - as soon as PR for FLINK-19681 is in working/test passing state. Are
you [~nicholasjiang] willing to work on that tight schedule and closely
coordinate with us?
