>                 Key: BEAM-3046
>                 URL: https://issues.apache.org/jira/browse/BEAM-3046
>             Project: Beam
>          Issue Type: Bug
>          Components: sdk-py-core
>            Reporter: Robert Bradshaw

> For example, though Java forces one to put all stand-alone functions as 
> static methods on a class (like Metrics) in Python one would just have 
> standard module-level functions. 
> Also, the MetricsFilter builder pattern is very Java-esque (and verbose). In 
> Python, one would simply let result.metrics() take keyword arguments. 
> We should seriously consider aggregating rather than returning lists of 
> results, at least by default. E.g. in 
> https://github.com/apache/beam/blob/master/sdks/python/apache_beam/examples/wordcount.py
>  it assumes that there's no other metric with the given name in any 
> subtransform (otherwise it may deterministically grab the "wrong" one.)
