[jira] [Created] (GOBBLIN-1100) Set average fetch time in the KafkaExtractor even when metrics are disabled

Hung Tran created GOBBLIN-1100:
----------------------------------

             Summary: Set average fetch time in the KafkaExtractor even when metrics are disabled
                 Key: GOBBLIN-1100
                 URL: https://issues.apache.org/jira/browse/GOBBLIN-1100
             Project: Apache Gobblin
          Issue Type: Bug
            Reporter: Hung Tran


The KafkaExtractor close method only calls the KafkaExtractorStatsTracker#emitTrackingEvents method when metrics instrumentation is enabled. This method calls KafkaExtractorStatsTracker#generateTagsForPartitions, which has the side effect of setting the average fetch time in the WorkUnitState. The average fetch time is required for the work unit packing to pack optimally.

 

Add a call to KafkaExtractorStatsTracker#generateTagsForPartitions in KafkaExtractor#close when metrics instrumentation is disabled to restore the behavior that existed prior to the KafkaExtractorStatsTracker refactoring.
