---------------------------------------

             Summary: Support Scala 3.x 
                 Key: SPARK-54150
                 URL: https://issues.apache.org/jira/browse/SPARK-54150
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core, SQL
    Affects Versions: 4.1.0
            Reporter: Norbert Schultz


Apache Spark should support Scala 3.x, together with Scala 2.13.x.

Scala 3.x. is now mature enough for using it in larger applications. Due to its 
better Macro, Tuple and generativ Support its very well suited to describe data 
processing applications. E.g. it's much easier to derive Database interfaces 
from case classes.

Altough Scala 2.13.x code can be called from Scala 3, the use of old fashioned 
Macros and transitive depedencies make it easier to use.
