> https://github.com/apache/spark/pull/59424, which replaces this PR, adds a test of Arrow UDFs over a native data source. Do you mean you'll support FFM only for the native implementation? > https://github.com/apache/spark/pull/59551 Looks like the PR introduced a full copy of every pass-through column of every batch. To Python UDF, the extra copy isn't a big issue. But we should be able to find way to avoid it. Reusing data is one of the main considerations we introduced with the Arrow data format. -- This is an automated message from the Apache Git Service.
