> Add ToSet() combiner, similar to ToList() and ToDict()
> ------------------------------------------------------
>
> Key: BEAM-9184
> URL: https://issues.apache.org/jira/browse/BEAM-9184
> Project: Beam
> Issue Type: New Feature
> Components: sdk-py-core
> Reporter: Jeffrey
> Priority: Minor
>
> ToList() doesn't do deduplication, and ToDict() requires key/value tuples.
> Sets are a different type than dicts in Python, so ToSet() is required to
> combine very large PCollections while deduplicating.
