What specific constraint cannot be enforced by Snowflake?

NOT NULL constraints
Foreign Key constraints
Primary Key constraints
CHECK constraints

The correct answer is: Foreign Key constraints

Foreign Key constraints in Snowflake are recognized for their value in data modeling, yet they are not enforced by the system. This means that while you can define relationships between tables using Foreign Keys for documenting purposes or reference, Snowflake does not actively enforce these relationships during data operations. The system allows for the establishment of data integrity through other means, like unique and NOT NULL constraints, which are actively enforced. Similarly, Primary Key constraints, while optional in terms of enforcement, help in denoting a unique identifier for each record in a table. CHECK constraints, used to ensure that values in a column meet a specific condition, are also enforced. This distinction highlights Snowflake’s architecture focusing on performance and flexibility, where users have the option to model relational structures but are not compelled to adhere to them strictly through enforcement of Foreign Key constraints.
