Enum Constant Summary

Enum Constants

Enum Constant and Description
COMPLEX Complex key generator, which takes names of fields to be used for recordKey and partitionPath as configs.
CUSTOM This is a generic implementation type of KeyGenerator where users can configure record key as a single field or a combination of fields.
GLOBAL_DELETE Key generator for deletes using global indices.
NON_PARTITION Simple Key generator for unpartitioned Hive Tables.
SIMPLE Simple key generator, which takes names of fields to be used for recordKey and partitionPath as configs.
TIMESTAMP Key generator, that relies on timestamps for partitioning field.

Enum Constant Detail

SIMPLE

public static final KeyGeneratorType SIMPLE

Simple key generator, which takes names of fields to be used for recordKey and partitionPath as configs.

COMPLEX

public static final KeyGeneratorType COMPLEX

Complex key generator, which takes names of fields to be used for recordKey and partitionPath as configs.

TIMESTAMP

public static final KeyGeneratorType TIMESTAMP

Key generator, that relies on timestamps for partitioning field. Still picks record key by name.

CUSTOM

public static final KeyGeneratorType CUSTOM

This is a generic implementation type of KeyGenerator where users can configure record key as a single field or a combination of fields. Similarly partition path can be configured to have multiple fields or only one field.

This KeyGenerator expects value for prop "hoodie.datasource.write.partitionpath.field" in a specific format. For example: properties.put("hoodie.datasource.write.partitionpath.field", "field1:PartitionKeyType1,field2:PartitionKeyType2").

NON_PARTITION

public static final KeyGeneratorType NON_PARTITION

Simple Key generator for unpartitioned Hive Tables.

GLOBAL_DELETE

public static final KeyGeneratorType GLOBAL_DELETE

Key generator for deletes using global indices.

Method Detail

values

public static KeyGeneratorType[] 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 (KeyGeneratorType c : KeyGeneratorType.values())
    System.out.println(c);

Returns:

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

valueOf

public static KeyGeneratorType 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
