andygrove opened a new issue, #4224: URL: https://github.com/apache/datafusion-comet/issues/4224
Higher-order functions like `exists`, `forall`, `transform`, `filter`, and `aggregate` currently fall back to Spark because they involve lambda expressions that Comet can't represent natively. With the JVM UDF bridge (#4170), we can evaluate these on the JVM while keeping data in columnar Arrow format — avoiding C2R/R2C transitions. Prototype for `exists` in #4223. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
