  • BLoad all data into Snowflake internal tables in a raw format (e.g., JSON or Parquet), and create
  • CStore all data in Snowflake internal tables in a fully normalized relational format, creating indexes
  • DUse only external tables to access data in cloud storage, avoiding any data loading into Snowflake
  • EIngest all data into a single Snowflake database, and use stored procedures to perform all data
