The StructType and StructField classes in PySpark are used to define the schema to the DataFrame and create complex columns such as nested struct, array, and map columns. StructType is a collection of StructField objects that determines column name, column data type, field nullability, and metadata. appName('ProjectPro').getOrCreate()

In the “assumptions” field, we see how the SQL AI Assistant looked over our data model; compared to what we’re looking for, it was able to find the right tables, columns, and joins needed to provide a query that will give us the list we’re looking for. And as a bonus, we even get the query written for us, saving us even more time!

Why is HDFS only suitable for large data sets and not the correct tool for many small files? NameNode is often given a large space to contain metadata for large-scale files. The metadata should come from a single file for optimal space use and economic benefit. And storing these metadata in RAM will become problematic.
