      Description

      The workaround for https://issues.apache.org/jira/browse/KAFKA-6607# Says:

      or use `consumer.position()` that takes the commit marker into account and would "step over it")

      Note that this problem occurs with all consumers, not just Streams. We have implemented this solution in our project (as an option for those users concerned about the pseudo lag).

      We have discovered that this technique will only work with 

      isolation.level=read_committed

      Otherwise, the 

      position()

      call does not include the marker "record".
