Anish Mahto updated SPARK-53890:
--------------------------------
Description:
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.
