catalog	Name of the top level of the requested table or view
schema	Name of the second most top level of the requested level or view

Details

These function are meant for downstream packages, that provide additional backends to 'sparklyr', to override the opening, closing, update, and preview functionality. The arguments are driven by what the RStudio IDE API expects them to be, so this is the reason why some use 'type' to designated views or tables, and others have one argument for 'table', and another for 'view'.
