Kenneth Knowles commented on BEAM-8529:
---------------------------------------
This will prevent {{Combine.globally}} from functioning, and
{{Combine.globally().asSingletonSideInput()}} is a pretty common pattern. I've
increased the priority to Critical because this is a broken primitive.
> Samza runner does not allow using Void as key in grouping operations
> --------------------------------------------------------------------
>
> Key: BEAM-8529
> URL: https://issues.apache.org/jira/browse/BEAM-8529
> Project: Beam
> Issue Type: Bug
> Components: runner-samza
> Affects Versions: 2.17.0
> Reporter: Jan Lukavský
> Priority: Critical
>
> Using {{Void}} as key type for grouping operations fails due to the fact that
> its only value is {{null}} and SamzaRunner does not accept using {{null}}
> values as keys. Other runners seem to work fine with that.
