> Hive already has support to declare multiple SQL constraints (PRIMARY KEY, FOREIGN KEY,
UNIQUE, and NOT NULL). Although these constraints cannot be currently enforced on the data,
they can be made available to the optimizer by using the 'RELY' keyword.
> Currently, even when they are declared with the RELY keyword, they are not exposed to
Calcite.
