hi
i have a flink sql, reading record from kafka, then use table function do some transformation, then produce to kafka. i have found that in the flink web record received of the first subTask is always 0 ,and the Records send of the last subTask is 0 as well. i want to count how many records i consumed from the source kafka and how many records i produce to the target kafka, how can i get these information from flink directly? best regards chong
