How to Convert Pyspark Dataframe to Pandas
In this tutorial we will see how to convert a pyspark dataframe into a pandas using the toPandas() function. Introduction After having processed the data in PySpark, we sometimes have to reconvert our pyspark dataframe to use some machine learning applications (indeed some machine learning models are not implemented in pyspark, for example XGBoost). However, the toPandas() function is one of the most expensive operations and should therefore be used with care, especially if we are dealing with large volumes of data. Pandas DataFrames are stored in RAM directly, this has the advantage of processing operations faster but is limited by…
