getOldTupleList

public List<ReplicationMessage.Column> getOldTupleList()

Specified by:

getOldTupleList in interface ReplicationMessage

Returns:

Set of original values of table columns, null for INSERT

getNewTupleList

public List<ReplicationMessage.Column> getNewTupleList()

Specified by:

getNewTupleList in interface ReplicationMessage

Returns:

Set of new values of table columns, null for DELETE

hasTypeMetadata

public boolean hasTypeMetadata()

Specified by:

isLastEventForLsn

public boolean isLastEventForLsn()

Specified by:

getValue

public static Object getValue(String columnName,
                              PostgresType type,
                              String fullType,
                              String rawValue,
                              PostgresStreamingChangeEventSource.PgConnectionSupplier connection,
                              boolean includeUnknownDataTypes,
                              TypeRegistry typeRegistry)

Converts the value (string representation) coming from PgOutput plugin to a Java value based on the type of the column from the message. This value will be converted later on if necessary by the connector's value converter to match whatever the Connect schema type expects. Note that the logic here is tightly coupled on the pgoutput plugin logic which writes the actual value.

Returns:

the value; may be null
