---------------------------------------

Due to the inactivity for last one month, I moved this test JIRA issue to the Apache Spark 4.2.0 for now. We can bring it back until the Apache Spark 4.1.0 release.

>          Components: Declarative Pipelines

> Add tests to verify read/readstream options are actually respected by the flow that executes the read/readstream dataframe.
> Trivial test example might be:
> {code:python}
> @materialized_view def mv_from_csv():
>    return spark.read.option("delimiter", "|").csv("/my/table.csv")
> {code}
> I suspect that today, the read/readstream options will not be respected ([1|https://github.com/apache/spark/blob/master/sql/pipelines/src/main/scala/org/apache/spark/sql/pipelines/graph/FlowAnalysis.scala#L120], [2)|#L131].
> If true, a solution might be to copy over the options in the `UnresolvedRelation` into either the DataFrameReader that is constructed or the `streamingReadOptions`/`batchReadOptions` argument.
