Discuss the challenges of converting a large PySpark DataFrame to a Pandas on Spark DataFrame and the potential solutions to mitigate these challenges. Provide a detailed example and explain the reasoning behind your solutions.
A
Converting a large PySpark DataFrame to a Pandas on Spark DataFrame can be challenging due to memory limitations, and the solution is to use the toPandas() method with distributed processing.
B
Converting a large PySpark DataFrame to a Pandas on Spark DataFrame can be challenging due to memory limitations, and the solution is to use the toPandas() method with incremental data collection and aggregation.
C
Converting a large PySpark DataFrame to a Pandas on Spark DataFrame can be challenging due to memory limitations, and the solution is to use the toPandas() method with data partitioning and parallel processing.
D
Converting a large PySpark DataFrame to a Pandas on Spark DataFrame can be challenging due to memory limitations, and the solution is to use the toPandas() method with data sampling and subsetting.
