Hello, Does Flink serialize all the data when moving from one operator to another (even when there is no shuffling/hashing between them)?
If yes, then, does it worth to have less operators doing more stuff instead of more granular operators? For instance, one flat map + one filter could be substituted with one flat map containing the filtering logic inside. That would minimize the serialization/deserialization between those two operators. It that so? Is that a recommended approach? Will that decrease GC? Thanks, Vadim.
