类 BinlogOffset

java.lang.Object

org.apache.seatunnel.connectors.cdc.base.source.offset.Offset

org.apache.seatunnel.connectors.seatunnel.cdc.mysql.source.offset.BinlogOffset

所有已实现的接口:

Serializable, Comparable<Offset>

public class BinlogOffset
extends Offset

A structure describes a fine grained offset in a binlog event including binlog position and gtid set etc.

This structure can also be used to deal the binlog event in transaction, a transaction may contains multiple change events, and each change event may contain multiple rows. When restart from a specific BinlogOffset, we need to skip the processed change events and the processed rows.
