A couple of items to double check if you are having issues . . .
If you have a successful connection between LityxIQ and Snowflake, and exporting data from Lityx to the Snowflake server is working great, but you can’t figure out how to get Snowflake data into LityxIQ. The connect is working, but for some reason no tables in the database are showing up in the LityxIQ platform. ANSWER: specify a compute warehouse in the Lityx connection details pane.
When trying to write to Snowflake: If LityxIQ is returning an error "did not include a schema. Please ensure there is a schema provided". Make sure you put the database name in the connection settings, not as part of the data schema in the export settings.
