Thanks ... I stand corrected on Snowflake storage layer being Azure Blob specifically. However, I meant to say snowflake mounts its custom (non open source) storage architecture on Azure Blob. Users can't access it directly... for more info read here https://www.snowflake.com/blog/how-to-get-started-with-snowflake-on-azure/

In regards to Snowflake acting as a source question....In one of my projects, we need to extract snowflake data into Azure SQL DB to power a AI application downstream. In that sense, I think we would not have performance issues
