YearMonthPartitionExpr

case class YearMonthPartitionExpr(yearPart: String, monthPart: String) extends OptimizablePartitionExpression with Product with Serializable

Optimize the case that two partition columns uses YEAR and MONTH using the same column, such as YEAR(eventTime) and MONTH(eventTime).

yearPart

the year partition column name

monthPart

the month partition column name
