Snowflake Pertanyaan dan Jawaban Wawancara
Ques 11. What is the difference between a transient and a multi-cluster virtual warehouse in Snowflake?
A transient virtual warehouse is designed for short-lived, bursty workloads, while a multi-cluster virtual warehouse is suitable for concurrent and long-running workloads. Transient warehouses are suspended when idle, saving costs.
Ques 12. Explain how Snowflake supports semi-structured data.
Snowflake natively supports semi-structured data formats like JSON and Avro. It can ingest, store, and query semi-structured data, providing flexibility for handling diverse data types.
Ques 13. What is Snowflake's approach to handling data sharing between different accounts?
Snowflake enables secure data sharing across different accounts through the use of shareable objects, such as databases, schemas, and tables. It allows controlled access to data without physical duplication.
Ques 14. How does Snowflake handle data encryption, both at rest and in transit?
Snowflake encrypts data at rest using AES-256 encryption. Data in transit is secured through SSL/TLS encryption. This ensures the confidentiality and integrity of data throughout its lifecycle.
Ques 15. What is the purpose of Snowflake's metadata services?
Snowflake's metadata services manage metadata related to objects stored in the data warehouse. This includes information about databases, tables, schemas, and user roles, facilitating efficient query optimization and execution.
