> In release 1.10, with FLIP-49, we introduced significant changes to the TaskExecutor
memory model and it's related configuration options / logics.
> Since the model and configuration logics are changed, it is reasonable that we also change
the default configuration values. Currently, the default values are set with the gut feelings
and experiences from e2e tests. It would be good that we try and tune the configurations with
some real production jobs, of various scales if possible, before exposing the configurations
in the release.
