Component/s: SQL
> Add metrics for data loss and offset out range for KafkaMicroBatchStream
> ------------------------------------------------------------------------
>
> Key: SPARK-34297
> URL: https://issues.apache.org/jira/browse/SPARK-34297
> Project: Spark
> Issue Type: Improvement
> Components: SQL, Structured Streaming
> Affects Versions: 3.2.0
> Reporter: L. C. Hsieh
> Assignee: L. C. Hsieh
> Priority: Major
>
> When testing SS, I found it is hard to track data loss of SS reading from
> Kafka. The micro scan node has only one metric, number of output rows. Users
> have no idea how many times offsets to fetch are out of Kafak now, how many
> times data loss happens.
