I know that we can make a parquet file from dataframe. Now suppose that, we have a class class like below:
case class Person(
id: String,
name: String,
roll: Option[Int]
)
Now, we have Seq[Person] and i want to make a parquet file from this sequence of person. In this case, we won't use spark.
So, How can we make a parquet file using scala/play from Seq[Person]?
