Package io.debezium.connector.informix

Class TxLogPosition

java.lang.Object

io.debezium.connector.informix.TxLogPosition

All Implemented Interfaces:

io.debezium.connector.Nullable, Comparable<TxLogPosition>

public class TxLogPosition
extends Object
implements io.debezium.connector.Nullable, Comparable<TxLogPosition>

Defines a position of change in the transaction log. The position is defined as a combination of commit LSN and sequence number of the change in the given transaction. The sequence number is monotonically increasing in transaction but it is not guaranteed across multiple transactions so the combination is necessary to get total order.
