[jira] [Created] (KAFKA-2993) compression-rate-avg always returns 0 event with compression.type being set

TAO XIAO created KAFKA-2993:
-------------------------------

             Summary: compression-rate-avg always returns 0 event with compression.type being set
                 Key: KAFKA-2993
                 URL: https://issues.apache.org/jira/browse/KAFKA-2993
             Project: Kafka
          Issue Type: Bug
            Reporter: TAO XIAO
            Assignee: TAO XIAO
            Priority: Minor


The producer metric compression-rate-avg always returns 0 even with compression.type set to snappy. I drilled down the code and discovered that the position of bytebuffer in org.apache.kafka.common.record.Compressor is reset to 0 by RecordAccumulator.drain() before calling metric updates in sender thread.
