How to integrate Python with Spark? What are the basic operations and building blocks of Spark that can be done using PySpark? In this PySpark tutorial, we will implement codes using the Fortune 500 dataset and implement our codes on it. This dataset contains data about the top five companies...
Solutions like this may be implemented with the PySparkfilterfunction or through SQL in PySpark. Both will be covered in thisPySpark Filtertutorial. We will go through examples using the filter function as well as SQL. Between the examples, we’ll pause to briefly discuss performance considerations...
We can use “withColumn” along with the “cast” function to achieve this. from pyspark.sql.types import StringType # Change the data type of the 'id' column to string df = df.withColumn("id", col("id").cast(StringType())) # Display the updated DataFrame df.show() +---+---+...
