my $snowflake = App::Sqitch::Engine->load( engine => 'snowflake' );
App::Sqitch::Engine::snowflake provides the Snowflake storage engine for Sqitch.

In the host name of the target URI. If that host name does not end in
snowflakecomputing.com, Sqitch appends it. This lets Snowflake URLs just reference the Snowflake account name or the account name and region in URLs.
By concatenating the account name and region, if available, from the
$SNOWSQL_ACCOUNTenvironment variable or
connections.accountnamesetting in the SnowSQL configuration file, the
connections.regionsetting in the SnowSQL configuration file, and
The port defaults to 443, but uses to the
$SNOWSQL_PORT environment variable if it's set. The database name is determined by the following methods:
