类 Offset

java.lang.Object

cn.tenmg.cdc.log.connectors.base.source.meta.offset.Offset

所有已实现的接口:

Serializable, Comparable<Offset>

@Experimental
public abstract class Offset
extends Object
implements Comparable<Offset>, Serializable

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 Offset, we need to skip the processed change events and the processed rows.
