Class FlinkRecordsWithSplitIds

java.lang.Object

org.apache.paimon.flink.source.FlinkRecordsWithSplitIds

All Implemented Interfaces:

org.apache.flink.connector.base.source.reader.RecordsWithSplitIds<org.apache.flink.connector.file.src.reader.BulkFormat.RecordIterator<org.apache.flink.table.data.RowData>>

public class FlinkRecordsWithSplitIds
extends Object
implements org.apache.flink.connector.base.source.reader.RecordsWithSplitIds<org.apache.flink.connector.file.src.reader.BulkFormat.RecordIterator<org.apache.flink.table.data.RowData>>

A RecordsWithSplitIds which contains only one iterator record. This can ensure that there will be no checkpoint segmentation in iterator consumption.
