Snowflake's distributed architecture allows fast processing of large datasets with scalable computing and storage. It offers clustering, pay-per-use, and flexible data integration, enhancing its performance and data sharing abilities. However, Snowflake faces challenges with geo-spatial queries, SQL-based stored procedures, unstructured data support, and AI capabilities. Improved external tool integration and a clearer pricing model are needed for better transparency and usability for technical buyers.
