**Simple Example for Basic Use Cases:**

This example shows adding a primary_key without column definition, which is a fallback option for backward compatibility and generates DeprecationWarnings.

result_table = ci.create_out_table_definition(
    'output.csv',
    primary_key=['id'],
    incremental=True,
    description='Data processed by my component'
)
