类 JdbcIncrementalSource<T>

java.lang.Object

cn.tenmg.cdc.log.connectors.base.source.JdbcIncrementalSource<T>

所有已实现的接口:

Serializable, org.apache.flink.api.connector.source.Source<T,SourceSplitBase,PendingSplitsState>, org.apache.flink.api.java.typeutils.ResultTypeQueryable<T>

@Experimental
public class JdbcIncrementalSource<T>
extends Object
implements org.apache.flink.api.connector.source.Source<T,SourceSplitBase,PendingSplitsState>, org.apache.flink.api.java.typeutils.ResultTypeQueryable<T>

The basic source of Incremental Snapshot framework for JDBC datasource, it is based on FLIP-27 and Watermark Signal Algorithm which supports parallel reading snapshot of table and then continue to capture data change by streaming reading.
