public DynamicTableSourceSpec getTableSourceSpec()

translateToPlanInternal

protected org.apache.flink.api.dag.Transformation<org.apache.flink.table.data.RowData> translateToPlanInternal(PlannerBase planner,
 ExecNodeConfig config)

Description copied from class: ExecNodeBase

Internal method, translates this node into a Flink operator.

Specified by:

translateToPlanInternal in class ExecNodeBase<org.apache.flink.table.data.RowData>

Parameters:

planner - The planner.

config - per-ExecNode configuration that contains the merged configuration from various layers which all the nodes implementing this method should use, instead of retrieving configuration from the planner. For more details check ExecNodeConfig.

getPhysicalRowType

protected org.apache.flink.table.types.logical.RowType getPhysicalRowType(org.apache.flink.table.catalog.ResolvedSchema schema)

getPrimaryKeyIndices

protected int[] getPrimaryKeyIndices(org.apache.flink.table.types.logical.RowType sourceRowType,
 org.apache.flink.table.catalog.ResolvedSchema schema)

createSourceFunctionTransformation

@Deprecated
protected org.apache.flink.api.dag.Transformation<org.apache.flink.table.data.RowData> createSourceFunctionTransformation(org.apache.flink.streaming.api.environment.StreamExecutionEnvironment env,
 org.apache.flink.streaming.api.functions.source.legacy.SourceFunction<org.apache.flink.table.data.RowData> function,
 boolean isBounded,
 String operatorName,
 org.apache.flink.api.common.typeinfo.TypeInformation<org.apache.flink.table.data.RowData> outputTypeInfo,
 int sourceParallelism,
 boolean sourceParallelismConfigured)

Deprecated.

This method relies on the SourceFunction API, which is due to be removed.

Adopted from StreamExecutionEnvironment.addSource(SourceFunction, String, TypeInformation) but with custom Boundedness.

createInputFormatTransformation

protected abstract org.apache.flink.api.dag.Transformation<org.apache.flink.table.data.RowData> createInputFormatTransformation(org.apache.flink.streaming.api.environment.StreamExecutionEnvironment env,
 org.apache.flink.api.common.io.InputFormat<org.apache.flink.table.data.RowData,?> inputFormat,
 org.apache.flink.table.runtime.typeutils.InternalTypeInfo<org.apache.flink.table.data.RowData> outputTypeInfo,
 String operatorName)

Creates a Transformation based on the given InputFormat. The implementation is different for streaming mode and batch mode.
