Enum Class Operation

java.lang.Enum<Operation>

com.hazelcast.jet.cdc.Operation

All Implemented Interfaces:

Serializable, Comparable<Operation>, Constable

@EvolvingApi
public enum Operation
extends Enum<Operation>

Describes the nature of a CDC event, mainly the type of action performed on a database record: insertion, update and deletion. There are also some special values: "sync", which has the same effect as an insert, but originates from the initial database snapshot (as opposed to the database changelog), and "unspecified", used for a few special CDC events (like heartbeats).

Since:

Jet 4.2

Enum Constant Summary

Enum Constants

Enum Constant	Description
DELETE	Record deletion, sourced from the DB changelog.
INSERT	Record insertion, sourced from the DB changelog.
SYNC	Just like INSERT, but coming from the initial DB snapshot (as opposed to the change log).
UNSPECIFIED	ChangeRecord doesn't have an operation field, for example heartbeats.
UPDATE	Record update, sourced from the DB changelog.

Method Summary

Modifier and Type	Method	Description
String	code()	Returns the Debezium operation code as String.
static Operation	get(String opcode)	Parses the string present in a CDC message into the corresponding Operation enum member.
static Operation	valueOf(String name)	Returns the enum constant of this class with the specified name.
static Operation[]	values()	Returns an array containing the constants of this enum class, in the order they are declared.

Enum Constant Details

UNSPECIFIED

public static final Operation UNSPECIFIED

ChangeRecord doesn't have an operation field, for example heartbeats.

SYNC

public static final Operation SYNC

Just like INSERT, but coming from the initial DB snapshot (as opposed to the change log).

INSERT

public static final Operation INSERT

Record insertion, sourced from the DB changelog.

UPDATE

public static final Operation UPDATE

Record update, sourced from the DB changelog.

DELETE

public static final Operation DELETE

Record deletion, sourced from the DB changelog.

Method Details

values

public static Operation[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static Operation valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null

code

public String code()

Returns the Debezium operation code as String.

get

public static Operation get(@Nullable
 String opcode)
                     throws ParsingException

Parses the string present in a CDC message into the corresponding Operation enum member.

If the argument is null, it returns UNSPECIFIED.

Throws:

ParsingException - if the input string doesn't represent an expected value
