Class VectorUDFDateTimestamp

java.lang.Object

org.apache.hadoop.hive.ql.exec.vector.expressions.VectorExpression

org.apache.hadoop.hive.ql.exec.vector.expressions.FuncTimestampToLong

org.apache.hadoop.hive.ql.exec.vector.expressions.CastTimestampToDate

org.apache.hadoop.hive.ql.exec.vector.expressions.VectorUDFDateTimestamp

All Implemented Interfaces:

Serializable

public class VectorUDFDateTimestamp
extends CastTimestampToDate

Vectorized version of TO_DATE(timestamp). As TO_DATE() now returns DATE type, this should be the same behavior as the DATE cast operator.
