Column-level data lineage is retived using Dataedo SQL parser. Read more about capabilities of Snowflake SQL parser.

Known limitations

  • Snowflake’s INFORMATION_SCHEMA currently doesn’t contain data on object dependencies or usage of COPY INTO statements. Information about dependencies and COPY INTO history is retrieved from the SNOWFLAKE.ACCOUNT_USAGE.OBJECT_DEPENDENCIES and SNOWFLAKE.ACCOUNT_USAGE.COPY_HISTORY views. By default, the SNOWFLAKE database is available only to the ACCOUNTADMIN role. Read more about Enabling Snowflake Database Usage for Other Roles.

Due to Snowflake Connector for .NET limitations:

  • Username and password
    • Cannot contain ; and = characters
  • Database, role and warehouse name
    • Cannot contain ; and ‘ or \ characters
