YearMonthDayHourPartitionExpr

case class YearMonthDayHourPartitionExpr(yearPart: String, monthPart: String, dayPart: String, hourPart: String) extends OptimizablePartitionExpression with Product with Serializable

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

yearPart

the year partition column name

monthPart

the month partition column name

dayPart

the day partition column name

hourPart

the hour partition column name
