Allow custom Snowflake host / connection string

[Amit-cloud-pr]

Hi Airbyte team,

We’re using Airbyte with Snowflake and would like to route the connection through a proxy (Yuki) instead of connecting directly to the standard Snowflake host.
Today, the Snowflake destination UI validates the “Host” field and only allows values that match:
{account_name}.snowflakecomputing.com or {account_name}.{aws_location}.aws.snowflakecomputing.com

Because of this, we can’t set a custom host like: yuki-proxy.comany_name.com
Our use case: We want Airbyte to connect to Snowflake via Yuki’s proxy layer (for optimization / routing / control).

Technically this works at the driver level, but the UI validation blocks it.nWe’d like support for either:

• A “Custom host” / “Advanced” option, or
• Disabling / relaxing host validation, or
• A full custom connection string field.

This would really help teams that use proxies, private networking, or custom Snowflake endpoints in front of Snowflake.
Thanks!
