Package io.debezium.connector.postgresql

Class UnchangedToastedReplicationMessageColumn

java.lang.Object

io.debezium.connector.postgresql.connection.AbstractReplicationMessageColumn

io.debezium.connector.postgresql.UnchangedToastedReplicationMessageColumn

All Implemented Interfaces:

ReplicationMessage.Column

public class UnchangedToastedReplicationMessageColumn
extends AbstractReplicationMessageColumn

Represents a toasted column in a ReplicationStream. Some decoder implementations may stream information about a column but provide an indicator that the field was not changed and therefore toasted. This implementation acts as an indicator for such fields that are contained within a ReplicationMessage.
