class atoti_directquery_snowflake.SnowflakeConnectionInfo#

Information needed to connect to a Snowflake database.

__init__(url, /, *, password=None, feeding_warehouse_name=None, array_agg_wrapper_function_name=None, time_travel=True)#

Create a Snowflake connection info.

  • url (str) – The JDBC connection string. See for more information.

  • password (str | None) –

    The password to connect to the database.

    Passing it in this separate parameter allows to avoid having it logged alongside the connection string.

    If None, a password is expected to be present in the passed url.

  • feeding_warehouse_name (str | None) – The name of the warehouse to use for the initial feeding. If None, the main warehouse will be used.

  • array_agg_wrapper_function_name (str | None) – The name of the User Defined Function to use to wrap the aggregations on arrays to improve performance. This function must be defined in Snowflake and accessible to the role running the queries.

  • time_travel (bool) – Whether to use time travel in queries.
