## What changes were proposed in this pull request? This change uses Arrow to optimize the creation of a Spark DataFrame from a Pandas DataFrame. The input df is sliced according to the default parallelism. The optimization is enabled with the existing conf "spark.sql.execution.arrow.enabled" and is disabled by default. ## How was this patch tested? Added new unit test to create DataFrame with and without the optimization enabled, then compare results.
