[jira] [Created] (KAFKA-13692) stream thread blocked-time-ns-total metric does not include producer metadata wait time

Rohan Desai created KAFKA-13692:
-----------------------------------

             Summary: stream thread blocked-time-ns-total metric does not include producer metadata wait time
                 Key: KAFKA-13692
                 URL: https://issues.apache.org/jira/browse/KAFKA-13692
             Project: Kafka
          Issue Type: Bug
          Components: streams
    Affects Versions: 3.2.0
            Reporter: Rohan Desai
             Fix For: 3.3.0


The stream thread blocked-time-ns-total metric does not include producer metadata wait time (time spent in `KafkaProducer.waitOnMetadata`). This can contribute significantly to actual total blocked time in some cases. For example, if a user deletes the streams sink topic, producers will wait until the max block timeout. This time does not get included in total blocked time when it should.
