Examples with RowtimeAttribute org.apache.flink.table.runtime.groupwindow.RowtimeAttribute used on opensource projects

Example 1 with RowtimeAttribute

use of org.apache.flink.table.runtime.groupwindow.RowtimeAttribute in project flink by apache.

the class BatchExecPythonGroupWindowAggregate method createPythonOneInputTransformation.

private OneInputTransformation<RowData, RowData> createPythonOneInputTransformation(Transformation<RowData> inputTransform, RowType inputRowType, RowType outputRowType, int maxLimitSize, long windowSize, long slideSize, Configuration pythonConfig, ExecNodeConfig config) {

        }
        if (property instanceof WindowEnd) {
            return 1;
        }
        if (property instanceof RowtimeAttribute) {
            return 2;
        }
        throw new TableException("Unexpected property " + property);
    }).toArray();
