Zhu Zhu commented on FLINK-32513:
-
{{Transformation}} is not a public interface, it is an @Internal class.
Ideally, kafka connectors should not directly manipulate {{Transformation}}.
Production-wise, we may take a look whether there is a workaround to avoid
break existing kafka connectors.

Martijn Visser commented on FLINK-32513:
[~jeyhunkarimov] That shouldn't be our starting point, especially since this
change has also been introduced in patch version. Meaning that all custom
connectors that users have built, could suddenly also no longer work with a
patch version. We could also potentially have to update all externalized
connectors, who might depend on this interface. Our starting point should be
introduce non-breaking changes. Specifics may very based on the interface
annotation.

Hi [~martijnvisser] Thanks for reporting it. Would it be possible to fix it in
kafka connector side, to make it compatible with releases 1.18 and 1.19?

Zhu Zhu commented on FLINK-32513:
-
The problem happens because the {{getTransitivePredecessors()}} of
{{TwoInputTransformation}} is not properly implemented, which results in a
2^N(N = number of TwoInputTransformation) time cost to iterate and space cost
to store the predecessors.
A possible solution can be adding a cache of predecessors for each
Transformation and using LinkedHashSet to deduplicate the predecessors.
Note that a few other transformations can lead to the same problem too, e.g.
UnionTransformation, AbstractMultipleInputTransformation.

Hi [~huwh] , this job is automatically generated by our config file parser. So
I can't give you Flink code example, but I can give you a pseudo description of
the task topology:
The job graph consists of a Kafka Source, 20 consecutive "Nodes" and a Kafka
Sink. Each "Node" represents 3 transformations shown in the picture.

Thanks [~vladislav.keda] reporting this. Could you provide the job topology to
help reproduce it?
