Hmmm I guess we could route to a simple GroupByKey if the runner doesn't support GroupIntoBatches. It wouldn't behave the same way because ALL rows in a partition will be processed by a single `@ProcessElement` call, whereas GroupIntoBatches will split it into separate batches of a particular size, one `@ProcessElement` call per batch. But I guess that's okay for smaller writes, and better than not grouping at all. I wonder if there's a way to programmatically determine if the specified runner supports `@OnWindowExpiration` or not though, so we can route it properly -- This is an automated message from the Apache Git Service.
