[GitHub] [spark] Kimahriman commented on pull request #39572: [SPARK-39979][SQL] Add option to use large variable width vectors for arrow UDF operations

Kimahriman commented on PR #39572:
URL: https://github.com/apache/spark/pull/39572#issuecomment-1531947878

   > Currently (before this PR) if I do a groupby -> `.applyInPandas`, does the 2GB limit apply to the whole group or just each column in the group?
   
   It's each column. And I think because of https://issues.apache.org/jira/browse/SPARK-42347 it's now limited to 1GB.
