Enum Constant Detail

COMMIT

public static final SourceTimestampMode COMMIT

This mode (default) will set the source timestamp field (ts_ms) of when the record was committed in the database.

PROCESSING

@Deprecated
public static final SourceTimestampMode PROCESSING

Deprecated.

Use COMMIT instead.

This mode will set the source timestamp field (ts_ms) of when the record was processed by Debezium.

Method Detail

values

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

Returns:

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

valueOf

public static SourceTimestampMode 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

getValue

public String getValue()

Specified by:

getValue in interface EnumeratedValue

getTimestamp

protected abstract Instant getTimestamp(Clock clock,
                                        ResultSet resultSet)
                                 throws SQLException

Returns the timestamp to be put in the source metadata of the event depending on the mode.

Parameters:

clock - System clock to source processing time from

resultSet - Result set representing the CDC event and its commit timestamp, if required by the mode

Throws:

SQLException

lsnTimestampSelectStatement

protected abstract String lsnTimestampSelectStatement()

Returns the SQL fragment to be embedded into the GET_ALL_CHANGES_FOR_TABLE query depending on the mode.

getResultColumnNames

protected List<String> getResultColumnNames(ResultSetMetaData rsmd,
                                            int columnDataOffset)
                                     throws SQLException

Returns the names of the data columns returned by the GET_ALL_CHANGES_FOR_TABLE query.

Parameters:

rsmd - Result set metadata

columnDataOffset - Offset of the first data column in the result set

Throws:

SQLException

getDefaultMode

public static SourceTimestampMode getDefaultMode()

fromMode

static SourceTimestampMode fromMode(String mode)
