+# column names can have an arbitrary amount of dots
+# here is how the resolution works:
+# no dots (i.e. "part1")
+# -> part1 refers to a column
+# one dot (i.e. "part1.part2")
+# EITHER:
+# -> part1 is a table, part2 is a column
+# -> part1 is a column, part2 is a property of that column (i.e. struct_extract)
+# two or more dots (i.e. "part1.part2.part3.part4...")
+# -> part1 is a schema, part2 is a table, part3 is a column name, part4 and beyond are struct fields
+# -> part1 is a table, part2 is a column name, part3 and beyond are struct fields
+# -> part1 is a column, part2 and beyond are struct fields
+
+# we always prefer the most top-level view
+# i.e. in case of multiple resolution options, we resolve in order:
+# -> 1. resolve "part1" as a schema
+# -> 2. resolve "part1" as a table
+# -> 3. resolve "part1" as a column
