KafkaSinglePortExactlyOnceOutputOperator 

Hi, Need some help with the errors we are having with" KafkaSinglePortExactlyOnceOutputOperator". When monitoring the application, We are observing that the operator getting inactive and  restarts continuously. Could anyone help us with identifying an issue?

Use case: kafka producer emits messages and processing messages using Datatorrent application, Based on the DT application logic divide the messages into two different groups and write it to two different Mapr strem topics.

Yes, it may be better to pull out the topic selection into an upstream
operator that emits the messages on separate ports per topic and then you
can use the exactly-once output operator without customization.

Just a correction for use case.

Use case: kafka producer emits messages and processing messages using Datatorrent application, Based on the DT application logic divide the messages into two different groups and write it to two different kafka topics

The operator recovery logic assumes that data is written to a single topic.
This may happen because it is writing multiple?
