Empty Objects
Objects with zero rows will not be downloaded. This also means that no tables will be created for empty objects. You can see the list of empty objects with:
select * from sfm.sfm_objects where is_queryable = 1 and cant_query = 0 and is_empty = 1
When rows are added to an empty object the is_empty flag will be removed on the next download. If the object is set to be downloaded tables will be created for it and all data will be downloaded automatically.
