hvanhovell opened a new pull request, #47921: URL: https://github.com/apache/spark/pull/47921
### What changes were proposed in this pull request? This PR moves Observation into sql/api. For classic I moved the wiring into the `observe` method itself, and the required listener is now part of the `org.apache.spark.sql.internal` package. I have also take the liberty to get rid of most of the homegrown locking, and I have replaced it with a promise. ### Why are the changes needed? We are creating a shared interface for the classic and connect Scala DataFrame API. This class is part of that API. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Existing tests. ### Was this patch authored or co-authored using generative AI tooling? No. -- This is an automated message from the Apache Git Service.
