----------------------------------------------
Summary: Implement optimization rewritings that rely on database
SQL constraints
Key: HIVE-17039
URL: https://issues.apache.org/jira/browse/HIVE-17039
Project: Hive
Issue Type: New Feature
Components: Logical Optimizer
Affects Versions: 3.0.0
Reporter: 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.
This ticket is an umbrella for all the rewriting optimizations based on SQL
constraints that we will be including in Hive.
