According to Snowflake best practices, transient tables (option C) are recommended when data can be recreated outside of Snowflake. Transient tables exist until explicitly dropped and do not have Fail-safe protection, with a maximum Time Travel retention period of 1 day. This provides significant storage cost savings compared to permanent tables, while temporary tables (option B) are session-scoped and would not persist beyond the current session, making them unsuitable for data that needs to be retained across sessions. The community discussion strongly supports option C with 100% consensus, highlighting the cost benefits and appropriate use case for transient tables when data is recreatable externally.
