Create a table from PythonDynamicTableSource that read data from input file with specific DataType.

参数:

tEnv - The TableEnvironment to create table.

filePath - the file path of the input data.

schema - The python data type.

batched - Whether to read data in a batch

返回:

Table with InputFormat.

getInputFormat

public static org.apache.flink.api.common.io.InputFormat<org.apache.flink.table.data.RowData,?> getInputFormat(List<Object[]> data,
                                                                                                               org.apache.flink.table.types.DataType dataType)

Wrap the unpickled python data with an InputFormat. It will be passed to PythonDynamicTableSource later.

参数:

data - The unpickled python data.

dataType - The python data type.

返回:

An InputFormat containing the python data.
