Encoders are Spark SQL's mechanism for converting a JVM type into a Catalyst representation.
Encoders are Spark SQL's mechanism for converting a JVM type into a Catalyst representation.
They are fetched from implicit scope whenever types move beween RDDs and Datasets. Because each
of the types supported below has a corresponding UDT, we are able to use a standard Spark Encoder
to construct these implicits.
