[jira] [Created] (SPARK-30423) Deprecate UserDefinedAggregateFunction

Erik Erlandson created SPARK-30423:
--------------------------------------

             Summary: Deprecate UserDefinedAggregateFunction
                 Key: SPARK-30423
                 URL: https://issues.apache.org/jira/browse/SPARK-30423
             Project: Spark
          Issue Type: Task
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Erik Erlandson
            Assignee: Erik Erlandson


Anticipating the merging of SPARK-27296, the legacy methodology for implementing custom user defined aggregators over untyped DataFrame based on UserDefinedAggregateFunction will be made obsolete. This class should be annotated as deprecated once the new capability is officially merged.
