Loading data from Snowflake to Hubspot can be achieved through three different methods: Snowflake CSV download, Reverse ETL, and SnowSQL command line. The Snowflake CSV download method involves exporting a query as a CSV file and importing it into Hubspot, which is easy to learn but may not be a long-term solution. Reverse ETL, on the other hand, allows for seamless data movement between Snowflake and Hubspot with scalability and automation capabilities, making it suitable for regular data syncing. The SnowSQL command line method provides flexibility in CSV downloads but requires manual imports and exports. Ultimately, choosing the best option depends on the frequency of data loading and personal comfort level with each method.
