------------------------------------
Assignee: Genmao Yu
> Use nano time to calculate 'processedRowsPerSecond' to avoid 'NaN'/'Infinity'
> -----------------------------------------------------------------------------
>
> Key: SPARK-29973
> URL: https://issues.apache.org/jira/browse/SPARK-29973
> Project: Spark
> Issue Type: Bug
> Components: Structured Streaming
> Affects Versions: 3.0.0
> Reporter: Genmao Yu
> Assignee: Genmao Yu
> Priority: Minor
>
> The {{"processingTimeSec"}} of batch may be less than 1 millis. As
> {{"processingTimeSec"}} is calculated in millis, so {{"processingTimeSec"}}
> equals 0L. If there is no data in this batch, the
> {{"processedRowsPerSecond"}} equals {{"0/0.0d"}}, i.e. {{"Double.NaN"}}. If
> there are some data in this batch, the {{"processedRowsPerSecond"}} equals
> {{"N/0.0d"}}, i.e. {{"Double.Infinity"}}.
