xinrong-meng opened a new pull request, #42079: URL: https://github.com/apache/spark/pull/42079
### What changes were proposed in this pull request? Implement Arrow `self_destruct` of `toPandas` for memory savings. 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. ### Why are the changes needed? Reach parity with vanilla PySpark. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? TBD -- This is an automated message from the Apache Git Service.
