> @TheNeuralBit in section 6.6.2 of programming guide under grouping aggregations, they have used GROUP transform in java for selecting multiple fields, should we show how select in python can be used here for multiple fields? I think the [GroupBy transform](https://beam.apache.org/releases/pydoc/current/apache_beam.transforms.core.html#apache_beam.transforms.core.GroupBy) is the best analogue in Python. There are some usage examples [here](https://github.com/apache/beam/blob/cb31b7b6494ffe69480bb590562129bee93d64d1/sdks/python/apache_beam/examples/snippets/transforms/aggregation/groupby_test.py) > Also has support for joins and complex joins been developed yet for python and GO? No neither Python nor Go has a high-level Join transform. -- This is an automated message from the Apache Git Service.
