> Add default stats to StreamingExecutionRelation
> -----------------------------------------------
>
> Key: SPARK-21988
> URL: https://issues.apache.org/jira/browse/SPARK-21988
> Project: Spark
> Issue Type: Improvement
> Components: Structured Streaming
> Affects Versions: 2.2.0
> Reporter: Jose Torres
> Assignee: Apache Spark
> Fix For: 2.3.0
>
>
> StreamingExecutionRelation currently doesn't implement stats.
> This makes some sense, but unfortunately the LeafNode contract requires that nodes which survive analysis implement stats, and StreamingExecutionRelation can indeed survive analysis when running explain() on a streaming dataframe.
> This value won't ever be used during execution, because StreamingExecutionRelation does *not* survive analysis on the execution path; it's replaced with each batch.
