I don't think it would be too hard to add support. Aggregation functions are implemented in Beam SQL as [CombineFns](https://beam.apache.org/releases/javadoc/2.28.0/org/apache/beam/sdk/transforms/Combine.CombineFn.html). They are defined in [BeamBuiltinAggregations](https://github.com/apache/beam/blob/master/sdks/java/extensions/sql/src/main/java/org/apache/beam/sdk/extensions/sql/impl/transform/BeamBuiltinAggregations.java). -- This is an automated message from the Apache Git Service.
