Dongjoon Hyun updated SPARK-30368:
----------------------------------
Affects Version/s: (was: 3.0.0)
3.1.0
> Add computed rows metric to InMemoryRelation and show in SQL UI
> ---------------------------------------------------------------
>
> Key: SPARK-30368
> URL: https://issues.apache.org/jira/browse/SPARK-30368
> Project: Spark
> Issue Type: Improvement
> Components: SQL, Web UI
> Affects Versions: 3.1.0
> Reporter: Max Thompson
> Priority: Minor
> Attachments: w-metric.png
>
>
> This is a follow-up JIRA for:
> https://issues.apache.org/jira/browse/SPARK-30367
> We should add a "number of computed rows" metric to InMemoryRelation. This
> will show the user how many rows were computed using the InMemoryRelation's
> cached plan (e.g. possibly zero rows if no data had to be computed, the same
> amount as total rows read if all rows had to be computed, some subset of the
> total rows read if some partitions had to be recomputed, etc) which would
> help with determining how much work was done for this part of the query.
> An example with the metric where the InMemoryRelation's data was fully
> computed from its plan:
