[jira] [Created] (FLINK-16344) Preserve nullability for nested types

Timo Walther created FLINK-16344:
------------------------------------

             Summary: Preserve nullability for nested types
                 Key: FLINK-16344
                 URL: https://issues.apache.org/jira/browse/FLINK-16344
             Project: Flink
          Issue Type: Sub-task
          Components: Table SQL / Planner
            Reporter: Timo Walther
            Assignee: Timo Walther


Currently, FlinkTypeFactory does not always preserve nullability attributes when handling nested types.

E.g. a table function that returns {{ROW<s STRING, sa ARRAY<STRING> NOT NULL>}} looses information to {{ROW<s STRING, sa ARRAY<STRING>>}}.

Same for built-in functions such as {{COLLECT}} which results in mismatches as mentioned in FLINK-14042.
