sealed trait UdfAdaptor[T] extends Serializable
Tells Feathr how to use UDFs that are defined in "external" non-Feathr UDF classes (i.e.
Tells Feathr how to use UDFs that are defined in "external" non-Feathr UDF classes (i.e. that don't extend from Feathr's AnchorExtractor or other UDF traits). An adaptor must match the external UDF class to a specific kind of Feathr UDF – see child traits below for the various options.
All "external" UDF classes are required to have a public default zero-arg constructor.
T
the internal Feathr UDF class whose behavior the external UDF can be translated to

object FeathrUdfPluginContext
A shared registry for loading UdfAdaptors, which basically can tell Feathr's runtime how to support different kinds of "external" UDFs not natively known to Feathr, but which have similar behavior to Feathr's.
