All Implemented Interfaces:

Serializable, org.apache.flink.api.common.state.CheckpointListener, org.apache.flink.streaming.api.operators.Input<org.apache.flink.api.java.tuple.Tuple2<Split,String>>, org.apache.flink.streaming.api.operators.KeyContext, org.apache.flink.streaming.api.operators.KeyContextHandler, org.apache.flink.streaming.api.operators.OneInputStreamOperator<org.apache.flink.api.java.tuple.Tuple2<Split,String>,org.apache.flink.table.data.RowData>, org.apache.flink.streaming.api.operators.SetupableStreamOperator<org.apache.flink.table.data.RowData>, org.apache.flink.streaming.api.operators.StreamOperator<org.apache.flink.table.data.RowData>, org.apache.flink.streaming.api.operators.StreamOperatorStateHandler.CheckpointedStreamOperator, org.apache.flink.streaming.api.operators.YieldingOperator<org.apache.flink.table.data.RowData>

public class MultiTablesReadOperator
extends org.apache.flink.streaming.api.operators.AbstractStreamOperator<org.apache.flink.table.data.RowData>
implements org.apache.flink.streaming.api.operators.OneInputStreamOperator<org.apache.flink.api.java.tuple.Tuple2<Split,String>,org.apache.flink.table.data.RowData>

The operator that reads the Tuple2<Split, String> received from the preceding CombinedAwareBatchSourceFunction or CombinedAwareStreamingSourceFunction. Contrary to the CombinedCompactorSourceFunction which has a parallelism of 1, this operator can have DOP > 1.
