🤔 THE QUESTION

How do we define an explicit user profile schema containing required IDs, usernames, and nullable bios?

💡 WHAT IS IT?

Combining StringType fields with varying boolean nullability flags to model user profile entities.

🎯 WHAT IS IT USED FOR?

Ingesting user profiles from REST API payloads and verifying text column constraints.

💻 EXAMPLE

from pyspark.sql.types import StructType, StructField, StringType

user_schema = StructType([
    StructField("user_id", StringType(), False),
    StructField("username", StringType(), False),
    StructField("bio", StringType(), True)
])
