HeartSaVioR opened a new pull request, #55249: URL: https://github.com/apache/spark/pull/55249
### What changes were proposed in this pull request? This PR proposes to support stream-stream non-outer join (Inner/LeftSemi) in Update mode. The expected behavior of Inner/LeftSemi join in Update mode is simply the same with Append mode (since there is no point of early-firing), hence this is bound to the definition of Update mode, "if the query doesn't contain aggregations, it is equivalent to Append mode". ### Why are the changes needed? At this point, this is just to enable the same workload between Append mode and Update mode with the same behavior. Future improvement can enable some workload which can work in Append mode and Update mode, with different behavior. (Consider Update mode as early-firing.) ### Does this PR introduce _any_ user-facing change? Yes, stream-stream non-outer join will be supported with Update mode. ### How was this patch tested? New tests. ### Was this patch authored or co-authored using generative AI tooling? Generated-by: Claude 4.6 Opus -- This is an automated message from the Apache Git Service.
