Enum InsertMode

java.lang.Object

java.lang.Enum<InsertMode>

org.apache.hudi.sql.InsertMode

All Implemented Interfaces:

Serializable, Comparable<InsertMode>

public enum InsertMode
extends Enum<InsertMode>

Insert mode for insert into pk-table.

Enum Constant Summary

Enum Constants

Enum Constant and Description
NON_STRICT In non-strict mode for insert into, we use insert operation to write data which allow writing the duplicate record.
STRICT In strict mode for insert into, we do the pk uniqueness guarantee for COW pk-table.
UPSERT In upsert mode for insert into, duplicate record on primary key will be updated.This is the default insert mode for pk-table.

Method Summary

Modifier and Type	Method and Description
static InsertMode	of(String value)
String	value()
static InsertMode	valueOf(String name) Returns the enum constant of this type with the specified name.
static InsertMode[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

UPSERT

public static final InsertMode UPSERT

In upsert mode for insert into, duplicate record on primary key will be updated.This is the default insert mode for pk-table.

STRICT

public static final InsertMode STRICT

In strict mode for insert into, we do the pk uniqueness guarantee for COW pk-table. For MOR pk-table, it has the same behavior with "upsert" mode.

NON_STRICT

public static final InsertMode NON_STRICT

In non-strict mode for insert into, we use insert operation to write data which allow writing the duplicate record.

Method Detail

values

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

Returns:

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

valueOf

public static InsertMode 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
