Github user tzulitai commented on the issue:
A few points to mention:
1. @StephanEwen there is already common idleness detection implemented
within `SourceContext`s, see `StreamSourceContexts`. The idleness detection,
however, is currently always disabled and we do not allow users to configure it.
2. I agree that we shouldn't add anything more to the connector, have also
discussed this offline with @aljoscha. We should maybe do this only as part of
the new connector rework that @tweise and I were talking about, in 1.6.
