I found several warning messages when I tested around ported Spark Pandas API Documents (https://issues.apache.org/jira/browse/SPARK-34885).
1. `spark.sql.execution.arrow.enabled` on Best Practice document
21/07/26 05:42:02 WARN SQLConf: The SQL config 'spark.sql.execution.arrow.enabled' has been deprecated in Spark v3.0 and may be removed in the future. Use 'spark.sql.execution.arrow.pyspark.enabled' instead of it.
2. `DataFrame.to_spark_io` on From/to other DBMSes document
/opt/spark/python/lib/pyspark.zip/pyspark/pandas/frame.py:4811: FutureWarning: Deprecated in 3.2, Use spark.to_spark_io instead. warnings.warn("Deprecated in 3.2, Use spark.to_spark_io instead.", FutureWarning)
At this time it worked but I think it's better to update API usage on those documents.
