Timo Walther updated FLINK-5177:
--------------------------------
Description: Currently, all fields of the Table API are marked as nullable
by default. A lot of null checking could be avoided if we would properly handle
nullability. Fields of tuples and POJOs with primitive fields can not be null.
Elements of primitive arrays too. It also includes parameters and return types
of user-defined scalar, table, and aggregate functions. (was: Currently, all
