> Make Dataset.showString() public
> --------------------------------
>
> Key: SPARK-39722
> URL: https://issues.apache.org/jira/browse/SPARK-39722
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.4.8, 3.3.0
> Reporter: Jatin Sharma
> Priority: Trivial
>
> Currently, we have {{.show}} APIs on a Dataset, but they print directly to
> stdout.
> But there are a lot of cases where we might need to get a String
> representation of the show output. For example
> * We have a logging framework to which we need to push the representation of
> a df
> * We have to send the string over a REST call from the driver
> * We want to send the string to stderr instead of stdout
> For such cases, currently one needs to do a hack by changing the Console.out
> temporarily and catching the representation in a ByteArrayOutputStream or
> similar, then extracting the string from it.
> Strictly only printing to stdout seems like a limiting choice.
>
> Solution:
> We expose APIs to return the String representation back. We already have the
> .{{{}showString{}}} method internally.
>
> We could mirror the current {{.show}} APIS with a corresponding
> {{.showString}} (and rename the internal private function to something else
> if required)
