> /**
> * Returns a `hashCode` of the logical query plan against this [[Dataset]].

> * @since 3.4.0

> def semanticHash(): Int{code}
> This has to be computed on the spark connect server to do this. Please extend
> the
> AnalyzePlanRequest and AnalyzePlanResponse messages for this.
> Also make sure this works in PySpark.
