Xinrong Meng updated SPARK-44486:
---------------------------------
Description:
Implement PyArrow `self_destruct` feature for `toPandas`
Now the Spark configuration
`spark.sql.execution.arrow.pyspark.selfDestruct.enabled` can be used to enable
PyArrow’s `self_destruct` feature in Spark Connect, which can save memory when
creating a Pandas DataFrame via `toPandas` by freeing Arrow-allocated memory
while building the Pandas DataFrame.
