Enum Constant Detail

FetchDeletedRows

public static final HiveTableScan.HiveTableScanTrait FetchDeletedRows

If this is a fully acid table scan fetch the deleted rows too. This can be done only with uncompacted delete deltas.

FetchInsertOnlyBucketIds

public static final HiveTableScan.HiveTableScanTrait FetchInsertOnlyBucketIds

Provide bucket and writeId for records coming from Insert only transactional tables. Can not be used for fully acid tables since those tables store this metadata in the RowId struct for each record.

Method Detail

values

public static HiveTableScan.HiveTableScanTrait[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (HiveTableScan.HiveTableScanTrait c : HiveTableScan.HiveTableScanTrait.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static HiveTableScan.HiveTableScanTrait valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
