object DatasetParser extends App
The DatasetParser
object demonstrates how to parse and process a CSV file containing movie metadata
into a structured dataset using Spark and an implicit StringTableParser
.
It showcases capabilities to handle parsing, error management, and displaying results.
This object extends the App
trait, making it directly executable as a Scala program.

Method to demonstrate parsing a CSV file containing movie metadata into a dataset.
Method to demonstrate parsing a CSV file containing movie metadata into a dataset. This method uses an implicit
StringTableParser
to parse the data and creates a dataset ofMovie
entities. If parsing is successful, it displays the first 10 rows of the dataset; otherwise, it throws an exception.- sparkSession
an implicit SparkSession required to execute Spark operations.
- returns
Unit; this method performs side effects like displaying the dataset and does not return any value.
