Field Detail

TYPE

public static final java.lang.String TYPE

Type String for this object. This is a pseudo-type (i.e. it doesn't correspond to anything in the database). It is also the property key for this object on a Table.

public HiveSkewProperties()

Method Detail

getType

public java.lang.String getType()

Description copied from interface: DBObject

Returns the type of this object. Valid types include things like tables, views, synonyms, and columns.

Returns:

a string describing the type of object.

getSkewedColumns

public DBObjectID[] getSkewedColumns()

Gets the ids of the columns, from the parent table, that the table is skewed by.

Returns:

column ids to skew by

setSkewedColumns

public void setSkewedColumns(DBObjectID... skewCols)

Sets the ids of the columns, from the parent table, that the table is skewed by.

Parameters:

skewCols - column ids to skew by

getSkewedValues

public HivePartition[] getSkewedValues()

Gets the values for the skewed columns that the table is skewed by. Each HivePartition object contains a "values" property value which is the skew value for each skewed column.

Returns:

the skew value information

setSkewedValues

public void setSkewedValues(HivePartition... partitions)

Sets the values for the skewed columns that the table is skewed by.

Parameters:

the - skew value information

addSkewedValue

public void addSkewedValue(HivePartition partition)

Adds a partition to partitions property (at the end).

Parameters:

partition - the partition to add

removeSkewedValue

public void removeSkewedValue(HivePartition partition)

Removes a partition from the partitions property.

Parameters:

partition - the partition to remove

getStoredAsDirectories

public java.lang.Boolean getStoredAsDirectories()

Gets whether the skewed values should be stored as directories. When this is true, it is also known as "list bucketing".

Returns:

true if the skew values should be stored as directories.

setStoredAsDirectories

public void setStoredAsDirectories(java.lang.Boolean store)

Sets whether the skew values should be stored as directories.

Parameters:

store - true to store as directories (list bucketing).
