There are no dates yet. Both Snowflake and Microsoft Fabric are planned after Databricks. Their platform profiles are drafted: the dialects, table formats, merge idioms, incremental tools, deployment units, sign-in methods and known traps the agent needs to know. Both connectors are built and tested only against simulated Snowflake and Fabric services; neither has run on a real account.
We would rather give you a date we can keep than a date we hope for, so we post each one on the news page when it is ready, together with the shapes whose templates pass their tests on that platform.
If you run Snowflake or Fabric today, you can still use the local parts, because golden tests on DuckDB do not need a platform. See what a platform profile is.
