IdentityPartitionExpr

case class IdentityPartitionExpr(partitionColumn: String) extends OptimizablePartitionExpression with Product with Serializable

The rules for the generation of identity expressions, used for partitioning on a nested column. Note: - Writing an empty string to a partition column would become null (SPARK-24438) so generated partition filters always pick up the null partition for safety.

partitionColumn

the partition column name used in the generation expression.
