----------------------------------------------
Summary: Expose SQL database constraints to Calcite
Key: HIVE-17054
URL: https://issues.apache.org/jira/browse/HIVE-17054
Project: Hive
Issue Type: Improvement
Components: Logical Optimizer
Affects Versions: 3.0.0
Reporter: Jesus Camacho Rodriguez
Assignee: Jesus Camacho Rodriguez
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.
