To use raw data in your Kyvos configuration, you need to first configure a connection setting which allows you to see the option to Enable raw data querying when designing cubes.
You can configure a connection to support Presto, Spark, or HIVE for SQL querying.
You can also configure a Snowflake connection to support raw data.
To switch from one connection type to another, you may need to disable the Is Default SQL Engine option in the currently used connection before you can enable it in the connection type you want to use.
To configure the connection, see Working with data connections.
To enable raw data for querying, see Working with non-materialized or raw data cubes.
