Class ColumnStatsUpdateWork

java.lang.Object

org.apache.hadoop.hive.ql.plan.ColumnStatsUpdateWork

All Implemented Interfaces:

Serializable, DDLDesc, DDLDesc.DDLDescWithWriteId

public class ColumnStatsUpdateWork
extends Object
implements Serializable, DDLDesc.DDLDescWithWriteId

ColumnStatsUpdateWork implementation. ColumnStatsUpdateWork will persist the colStats into metastore. Work corresponds to statement like ALTER TABLE src_stat UPDATE STATISTICS for column key SET ('numDVs'='1111','avgColLen'='1.111'); ALTER TABLE src_stat_part PARTITION(partitionId=100) UPDATE STATISTICS for column value SET ('maxColLen'='4444','avgColLen'='44.4');
