I agree with @kennknowles. I took a look as well and it seems that DStream Spark runner uses only a global watermark updated when the microbatch ends instead of when new elements arrive. That seems similar to the issue we're having on the Dataset runner: see [watermark issue](https://echauchot.blogspot.com/2020/11/watermark-architecture-proposal-for.html) -- This is an automated message from the Apache Git Service.
