title: Flink StreamSink and Checkpoint Understanding
body: <p>I have written a job where 5 different source and sink is there in a single application. i am writing the data in parquet format using stream sink. As parquet sink write data on checkpoint. If one of the source get some malform records than i am getting exception in sink.
  But that causing my all the consumer to getting stopped. I am not able to write any data by other sinks also.</p>
  
  <p>Example:</p>
  
  <p>source1(kafka)---sink1(s3)
  source2(kafka) -sink2(s3)
  source3(kafka) - sink3(s3)</p>
