In my flink kafka streaming application i am fetching data from one topic
and then process and sent to output topic . my application is working fine
but flink dashboard shows Source [Bytes/records Received] and Sink
[Bytes/records sent] is zero.
Duration Name Bytes Records Bytes
3m 15s Source: Custom Source 0 B 0 249 MB
3m 15s Map -> Sink: Unnamed 203 MB 2,883 0 B 0
what is the reason for not showing correct number ?
