spark.python.profile: AddSQL_GROUPED_AGG_PANDAS_ITER_UDFto the profiler warning list inudf.pyso that whenspark.python.profileis enabled, users will see appropriate warnings consistent with other iterator-based UDFs.spark.sql.pyspark.udf.profiler: No changes needed. This UDF type already works correctly because it returns scalar (not iterator), so it uses the non-iterator profiler branch inwrap_perf_profilerandwrap_memory_profiler.Why are the changes needed?
To make profilers support for
SQL_GROUPED_AGG_PANDAS_ITER_UDFconsistent with other UDFs.Does this PR introduce any user-facing change?
Yes. When users enable
spark.python.profilewithSQL_GROUPED_AGG_PANDAS_ITER_UDF, they will now see a warning message consistent with other iterator-based UDFs.How was this patch tested?
Added a test case
test_perf_profiler_pandas_udf_grouped_agg_iterto verify thatspark.sql.pyspark.udf.profilerworks correctly with this UDF type. Also verified that thespark.python.profileprofiler warning is triggered correctly intest_unsupported.Was this patch authored or co-authored using generative AI tooling?
No.
