bx123 commented on FLINK-24915:
-------------------------------
[~arvid]
[#FLINK-5017] introduced StreamStatus support for this serializer, while it
does not handle streamstatus when object is reused in method
deserialize(StreamElement reuse, DataInputView source).
And [#FLINK-1137] said object reuse is not support in current flink version. So
I guess maybe this is why this problem not occur in production. Is this right?
flink-1137 is implemented in 2015 and I am not sure the status about object
reuse in current version.
Can you help me on this issue? thanks!
