To add a schema, you must create a new data source and associate it with that
schema. On the Data tab, click the “Add Data Source” button to add a new data
source. As part of this flow, you will see a ‘plus’ sign next to the schemas
dropdown, which you can click to enter a schema name. This data source will
automatically be assigned as the default data source for your new schema, and
you will be prompted to sync tables on connection to the data source.
To manage schema, navigate to the Data tab and click the Manage Schemas button.
From here, you can edit the names of your schema, change the default data
source, and delete your schema.When changing the default data source for a schema, it is recommended that you
then sync tables for that data source again.Deleting a schema is an operation that should only be done if absolutely
necessary. When you delete a schema, all data sources linked to that schema will
be deleted. Because these data sources may be powering queries in your
dashboards, you cannot delete a schema that has any datasets linked to that
schema. You must first manually delete those data sets from the Dashboard editor
before deleting the schema itself.
