类 JdbcSourceEventDispatcher

java.lang.Object

io.debezium.pipeline.EventDispatcher<io.debezium.relational.TableId>

cn.tenmg.cdc.log.connectors.base.relational.JdbcSourceEventDispatcher

public class JdbcSourceEventDispatcher
extends io.debezium.pipeline.EventDispatcher<io.debezium.relational.TableId>

A subclass implementation of EventDispatcher.

  1. This class shares one ChangeEventQueue between multiple readers.
  2. This class override some methods for dispatching HistoryRecord directly,
     this is useful for downstream to deserialize the HistoryRecord back.
