Changed my mind, Answer is 'A' The most performant file format for loading data in Snowflake is Parquet. According to Snowflake's official documentation, Parquet is a columnar storage file format that provides efficient data compression and encoding schemes, which improves performance for both storage and query execution

Selected Answer: B
Loading from Gzipped CSV is several times faster than loading from ORC and Parquet at an impressive 15 TB/Hour. While 5-6 TB/hour is decent if your data is originally in ORC or Parquet, don’t go out of your way to CREATE ORC or Parquet files from CSV in the hope that it will load Snowflake faster. https://community.snowflake.com/s/article/How-to-Load-Terabytes-Into-Snowflake-Speeds-Feeds-and-Techniques#:~:text=Loading%20data%20into%20Snowflake%20is,into%20fully%20structured%20Snowflake%20tables.
