About the snowflake course in Pune
Snowflake ETL refers to the process of extracting, transforming, and loading data into the Snowflake data warehouse. Snowflake is a cloud-based data warehousing platform that offers scalable storage and processing capabilities for handling large volumes of data.
Snowflake's architecture is designed to separate storage and compute, allowing for elastic scalability and performance optimization. This architecture enables Snowflake to handle large volumes of data and provide fast query response times, making it suitable for ETL processes involving massive datasets.
