-----------------------------------
Summary: Improve nullability handling
Key: FLINK-5177
URL: https://issues.apache.org/jira/browse/FLINK-5177
Project: Flink
Issue Type: Improvement
Components: Table API & SQL
Reporter: Timo Walther
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.
