AriadneInternalHelper

object AriadneInternalHelper

Bridge helper to access private[sql] Spark APIs from Ariadne.

This follows the standard pattern used by Delta Lake and other Spark connectors: placing a helper in the org.apache.spark.sql package to access private[sql] members like Dataset.ofRows.
