+## Specifying the Schema as Table Function Parameter
+
+Starting from Drill 1.17, table schema may be indicated in the query using table function.
+
+It is useful when the user does not want to persist schema in table root location or when reading from file, not folder.
+Schema parameter can be used as an individual unit or together with format plugin table properties.
