Data Pipelines: Copy data from Snowflake using on-prem gateway

Hi mark_carlisle 
Thanks for using Fabric Community.

There isn't official confirmation about direct Snowflake support within Data Pipelines for Microsoft Fabric at this time. However, there are some clues that can help:

1. On-prem Gateway Preview: The blog post mentioning on-prem gateway support in public preview suggests Microsoft Fabric is working on enabling access to external data sources. Snowflake might be included in future updates. If you want Snowflake to be included you can provide the feedback,which would be open for the user community to upvote & comment on. This allows our product teams to effectively prioritize your request against our existing feature backlog and gives insight into the potential impact of implementing the suggested feature.

2. Existing Snowflake Connector: Microsoft Fabric already offers a Snowflake connector which is Mirroring Snowflake. Mirroring provides an easy experience to avoid complex ETL (Extract Transform Load) and integrate existing your Snowflake warehouse data with the rest of your data in Microsoft Fabric. You can continuously replicate your existing Snowflake data directly into Fabric's OneLake. For more information please refer to this link: https://learn.microsoft.com/en-us/fabric/database/mirrored-database/snowflake
   
   

Hope this helps. Please let me know if you have any further questions.
