URL: https://github.com/apache/beam/pull/12779#issuecomment-691342588
> @epicfaace Curious, what use-case do you have in mind for this change?
I'm creating a Dataflow template in which I need to write to multiple
different output tables, "[prefix]_a", "[prefix]_b", "[prefix]_c", etc. I'd
like to be able to specify a single runtime parameter, "prefix", and derive the
output table names from this parameter, rather than having to redundantly
specify each table name as an input runtime parameter.
I noticed that [this
page](https://cloud.google.com/dataflow/docs/guides/templates/creating-templates#using-nestedvalueprovider)
said that the Apache Beam SDK for Python does not support NestedValueProvider,
so I just implemented it in Python in a similar way to how the Java SDK does it.
