Dawid Wysakowicz commented on FLINK-13384:
------------------------------------------
After further investigation I found out that it does not work only for
{{StreamSource}}s. I think it is caused by: [FLINK-12483]. The reason is that
the {{BackPressureStatsTrackerImpl}} samples only the main thread. FLINK-12483
introduced a separate thread for executing the sources in the mailbox model. It
is similar to other old bug that concerned only Kafka source: [FLINK-3456]
[~pnowojski] [~1u0] Could you verify if this is the case?
