Snowflake offers a distributed architecture for scalable data processing with separate compute and storage for cost optimization. It excels in data sharing and includes features like Time Travel and Zero Copy Cloning. While Snowflake boasts rapid query performance and supports diverse data types, it struggles with SQL-based stored procedures, pricing transparency, support responsiveness, unstructured data handling, machine learning, and seamless data integration, challenging some potential users.
